  <li>[http://maximum.room.ne.jp/bbs/sawa/yybbs.cgi http://maximum.room.ne.jp/bbs/sawa/yybbs.cgi]</li>
=== Enumeration ===
 
 
</ul>
There are 64 convex uniform polychora, including the 6 regular convex polychora, and excluding the infinite sets of the [[duoprism]]s and the antiprismatic hyperprisms.
* 5 are polyhedral prisms based on the [[Platonic solid]]s (1 overlap with regular since a cubic hyperprism is a [[tesseract]])
* 13 are polyhedral prisms based on the [[Archimedean solid]]s
* 9 are in the self-dual regular A<sub>4</sub> [3,3,3] group ([[5-cell]]) family.
* 9 are in the self-dual regular F<sub>4</sub> [3,4,3] group ([[24-cell]]) family. (Excluding snub 24-cell)
* 15 are in the regular BC<sub>4</sub> [3,3,4] group ([[tesseract]]/[[16-cell]]) family (3 overlap with 24-cell family)
* 15 are in the regular H<sub>4</sub> [3,3,5] group ([[120-cell]]/[[600-cell]]) family.
* 1 special snub form in the [3,4,3] group ([[24-cell]]) family.
* 1 special non-Wythoffian polychoron, the grand antiprism.
* TOTAL: 68 &minus; 4 = 64
 
These 64 uniform polychora are indexed below by [[George Olshevsky]]. Repeated symmetry forms are indexed in brackets.
 
In addition to the 64 above, there are 2 infinite prismatic sets that generate all of the remaining convex forms:
* Set of [[uniform antiprismatic hyperprism|uniform antiprismatic prism]]s - sr{p,2}×{&nbsp;} - Polyhedral prisms of two [[antiprisms]].
* Set of uniform [[duoprism]]s - {p}×{q} - A product of two polygons.
 
=== The A<sub>4</sub> family ===
 
The 5-cell has [[Pentachoric symmetry|''diploid pentachoric'' [3,3,3] symmetry]], of [[Symmetry order|order]] 120, isomorphic to the permutations of five elements, because all pairs of vertices are related in the same way.
 
Facets (cells) are given, grouped in their Coxeter diagram locations by removing specified nodes.

The three polychora forms marked with an [[asterisk]],'''*''', have the higher [[Pentachoric symmetry|extended pentachoric symmetry]], of order 240, [<span/>[3,3,3]<span/>] because the element corresponding to any element of the underlying 5-cell can be exchanged with one of those corresponding to an element of its dual. There is one small index subgroup [3,3,3]<sup>+</sup>, order 60, or its doubling [<span/>[3,3,3]<span/>]<sup>+</sup>, order 120, defining a [[full snub 5-cell]] which is listed for completeness, but is not uniform.

==== Coordinates ====
 
The coordinates of uniform 4-polytopes with pentachoric symmetry can be generated as permutations of simple integers in 5-space, all in hyperplanes with normal vector (1,1,1,1,1). The A<sub>4</sub> [[Coxeter group]] is [[palindrome|palindromic]], so repeated polytopes exist in pairs of dual configurations. There are 3 symmetric positions, and 6 pairs making the total 15 permutations of one or more rings. All 15 are listed here in order of [[binary arithmetic]] for clarity of the coordinate generation from the rings in each corresponding Coxeter diagram diagram.
 
The number of vertices can be deduced here from the [[permutation]]s of the number of coordinates, peaking at 5 [[factorial]] for the omnitruncated form with 5 unique coordinate values.

:(*) Just as rectifying the [[tetrahedron]] produces the [[octahedron]], rectifying the 16-cell produces the 24-cell, the regular member of the following family.
 
The ''snub 24-cell'' is repeat to this family for completeness. It is an alternation of the ''cantitruncated 16-cell'' or ''truncated 24-cell'', with the half symmetry group [(3,3)<sup>+</sup>,4]. The truncated octahedral cells become icosahedra. The cubes becomes tetrahedra, and 96 new tetrahedra are created in the gaps from the removed vertices.
 
==== Graphs ====
 
The pictures are drawn as [[Schlegel diagram]] perspective projections, centered on the cell at pos. 3, with a consistent orientation, and the 16 cells at position 0 are shown solid, alternately colored.

: (*) Like the 5-cell, the 24-cell is self-dual, and so the three asterisked forms have twice as many symmetries, bringing their total to 2304 ([[Icositetrachoric symmetry|extended icositetrachoric symmetry]] [<span/>[3,4,3]<span/>]).

==== Coordinates ====
 
Vertex coordinates for all 15 forms are given below, including dual configurations from the two regular 24-cells. (The dual configurations are named in bold.) Active rings in the first and second nodes generate points in the first column. Active rings in the third and fourth nodes generate the points in the second column. The sum of each of these points are then permutated by coordinate positions, and sign combinations. This generates all vertex coordinates. Edge lengths are 2.
 
The only exception is the snub 24-cell, which is generated by ''half'' of the coordinate permutations, only an even number of coordinate swaps. φ=(√5+1)/2.

=== The D<sub>4</sub> family ===
 
This [[Demitesseractic symmetry|demitesseract family]], [3<sup>1,1,1</sup>], introduces no new uniform polychora, but it is worthy to repeat these alternative constructions. This family has [[Symmetry order|order]] 12*16=192: 4!/2=12 permutations of the four axes, half as alternated, 2<sup>4</sup>=16 for reflection in each axis. There is one small index subgroups that generating uniform polychora, [3<sup>1,1,1</sup>]<sup>+</sup>, order 96.

When the 3 bifurcated branch nodes are identically ringed, the symmetry can be increased by 6, as [3[3<sup>1,1,1</sup>]] = [3,4,3], and thus these polytopes are repeated from the [[24-cell]] family.

Here again the ''snub 24-cell'', with the symmetry group [3<sup>1,1,1</sup>]<sup>+</sup> this time, represents an alternated truncation of the truncated 24-cell creating 96 new tetrahedra at the position of the deleted vertices. In contrast to its appearance within former groups as partly snubbed polychoron, only within this symmetry group it has the full analogy to the Kepler snubs, i.e. the [[snub cube]] and the [[snub dodecahedron]].

==== Coordinates ====
 
The ''base point'' can generate the coordinates of the polytope by taking all coordinate permutations and sign combinations. The edges' length will be √2. Some polytopes have two possible generator points. Points are prefixed by ''Even'' to imply only an even count of sign permutations should be included.

===The grand antiprism===
There is one non-Wythoffian uniform convex polychoron, known as the [[grand antiprism]], consisting of 20 [[pentagonal antiprism]]s forming two perpendicular rings joined by 300 [[tetrahedron|tetrahedra]].  It is loosely analogous to the three-dimensional [[antiprism]]s, which consist of two parallel [[polygon]]s joined by a band of [[triangle]]s. Unlike them, however, the grand antiprism is not a member of an infinite family of uniform polytopes.
 
Its symmetry is the ''ionic diminished Coxeter group'', [[10,2<sup>+</sup>,10]], order 400.

===Prismatic uniform polychora===
 
A prismatic polytope is a [[Cartesian product]] of two polytopes of lower dimension; familiar examples are the 3-dimensional [[prism (geometry)|prisms]], which are products of a [[polygon]] and a [[line segment]].  The prismatic uniform polychora consist of two infinite families:
* ''Polyhedral prisms'': products of a line segment and a uniform polyhedron.  This family is infinite because it includes prisms built on 3-dimensional prisms and [[antiprism]]s.
* ''Duoprisms'': products of two polygons.
 
==== Convex polyhedral prisms ====
The most obvious family of prismatic polychora is the ''polyhedral prisms,'' i.e. products of a polyhedron with a [[line segment]].  The cells of such a polychoron are two identical uniform polyhedra lying in parallel [[hyperplane]]s (the ''base'' cells) and a layer of prisms joining them (the ''lateral'' cells).  This family includes prisms for the 75 nonprismatic [[uniform polyhedron|uniform polyhedra]] (of which 18 are convex; one of these, the cube-prism, is listed above as the ''tesseract'').{{Citation needed|date=January 2011}}
 
There are '''18 convex polyhedral prisms''' created from 5 [[Platonic solid]]s and 13 [[Archimedean solid]]s as well as for the infinite families of three-dimensional [[prism (geometry)|prism]]s and [[antiprism]]s.{{Citation needed|date=January 2011}}  The symmetry number of a polyhedral prism is twice that of the base polyhedron.
 
==== Tetrahedral prisms: A<sub>3</sub> × A<sub>1</sub> ====
 
This [[Hexadecachoric symmetry|prismatic tetrahedral symmetry]] is [3,3,2], order 48. There are two index 2 subgroups, [(3,3)<sup>+</sup>,2] and [3,3,2]<sup>+</sup>, but the second doesn't generate a uniform polychoron.

==== Duoprisms: [p] × [q] ====
[[File:3-3 duoprism.png|thumb|The simplest of the duoprisms, the 3,3-duoprism, in [[Schlegel diagram]], one of 6 [[triangular prism]] cells shown.]]
The second is the infinite family of [[duoprism|uniform duoprisms]], products of two [[regular polygon]]s. A duoprism's [[Coxeter-Dynkin diagram]] is {{CDD|node_1|p|node|2|node_1|q|node}}. Its [[vertex figure]] is an [[disphenoid tetrahedron]], [[File:Pq-duoprism verf.png|75px]].
 
This family overlaps with the first: when one of the two "factor" polygons is a square, the product is equivalent to a hyperprism whose base is a three-dimensional prism.  The symmetry number of a duoprism whose factors are a ''p''-gon and a ''q''-gon (a "''p,q''-duoprism") is 4''pq'' if ''p''≠''q''; if the factors are both ''p''-gons, the symmetry number is 8''p''<sup>2</sup>. The tesseract can also be considered a 4,4-duoprism.
 
The elements of a ''p,q''-duoprism (''p'' ≥ 3, ''q'' ≥ 3) are:
* Cells: '''p''' ''q''-gonal prisms, '''q''' ''p''-gonal prisms
* Faces: '''pq''' squares, '''p''' ''q''-gons, '''q''' ''p''-gons
* Edges: '''2pq'''
* Vertices: '''pq'''
 
There is no uniform analogue in four dimensions to the infinite family of three-dimensional [[antiprism]]s.
 
Infinite set of '''p-q duoprism''' - {{CDD|node_1|p|node|2|node_1|q|node}} - '''p''' ''q''-gonal prisms, '''q''' ''p''-gonal prisms:

==== Polygonal prismatic prisms: [p] × [ ] × [ ] ====
 
The infinite set of uniform prismatic prisms overlaps with the 4-p duoprisms: (p≥3) - {{CDD|node_1|p|node|2|node_1|2|node_1}} - ''p'' cubes and 4 ''p''-gonal prisms - (All are the same as '''4-p duoprism''')
{{Convex prismatic prisms}}
 
The infinite sets of '''[[uniform antiprismatic prism]]s''' are constructed from two parallel uniform [[antiprism]]s): (p≥2) - {{CDD|node_h|p|node_h|2x|node_h|2|node_1}} - 2 ''p''-gonal antiprisms, connected by 2 ''p''-gonal prisms and ''2p'' triangular prisms.
{{Convex_antiprismatic_prisms}}
 
A ''p-gonal antiprismatic prism'' has ''4p'' triangle, ''4p'' square and ''4'' p-gon faces. It has ''10p'' edges, and ''4p'' vertices.

There are a number of [[Alternation (geometry)|alternations]] of the uniform polychora that can not be made uniform as they have too many parameters to satisfy.
 
Four [[Snub (geometry)|snubs]] are not uniform unlike their 3-dimensional analogies. Only the [[snub 24-cell]] is uniform, although it is more accurately called a ''semisnub 24-cell'' or ''snub demitesseract'' for being a full snub of the bifurcating family D<sub>4</sub> with the demitesseract as the alternated tesseract.
* [[Full snub 5-cell]] (snip), ht<sub>0,1,2,3</sub>{3,3,3}, {{CDD|node_h|3|node_h|3|node_h|3|node_h}}, 10 [[icosahedron]]s, 20 [[octahedron]]s, and 60 [[tetrahedron]]s, with [[Pentachoric symmetry|chiral extended pentachoric symmetry]], [<span/>[3,3,3]<span/>]<sup>+</sup>, order 120.
* [[Full snub tesseract]] (snet), ht<sub>0,1,2,3</sub>{4,3,3}, {{CDD|node_h|4|node_h|3|node_h|3|node_h}}, with 16 [[icosahedron]]s, 32 [[octahedra]], 24 [[square antiprism]]s, 8 [[snub cube]]s and 192 [[tetrahedron]]s, with [[Hexadecachoric symmetry|chiral hexadecachoric symmetry]], [4,3,3]<sup>+</sup>, order 192.
* The ''runcic snub rectified 16-cell'', {{CDD|node_1|4|node_h|3|node_h|3|node_h}}, has 176 cells, 656 faces, 672 edges, and 192 vertices. Its symmetry is [[4,(3,3,3)<sup>+</sup>]], order 192.
* [[Full snub 24-cell]] (snico), ht<sub>0,1,2,3</sub>{3,4,3}, {{CDD|node_h|3|node_h|4|node_h|3|node_h}}, from 48 [[snub cube]]s, 192 [[octahedron]]s, and 576 [[tetrahedron]]s, with [[Icositetrachoric symmetry|chiral extended icositetrachoric symmetry]], [<span/>[3,4,3]<span/>]<sup>+</sup>, order 1152.
* [[Runcic snub 24-cell]] (prissi), s<sub>3</sub>{3,4,3}, {{CDD|node_h|3|node_h|4|node|3|node_1}}, from 24 [[icosahedron]]s, 24 [[truncated tetrahedron]]s, 96 [[triangular prism]]s, and 96 [[triangular cupola]] in the gaps, for a total of 240 cells, 960 faces, 1008 edges, and 288 vertices. It is [[vertex-transitive]], and equilateral, but not uniform, due to the cupola. Like the [[snub 24-cell]], it has symmetry [3<sup>+</sup>,4,3], order 576.<ref>{{KlitzingPolytopes|polychora.htm|4D|s3s4o3x}}</ref>
* [[Full snub 120-cell]] (snahi), ht<sub>0,1,2,3</sub>{5,3,3}, {{CDD|node_h|5|node_h|3|node_h|3|node_h}}, 1200 [[octahedron]]s, 600 [[icosahedron]]s, 720 [[pentagonal antiprism]]s, 120 [[snub dodecahedron]]s, and 7200 [[tetrahedron]]s, with [[Hexacosichoric symmetry|chiral hexacosichoric symmetry]], [5,3,3]<sup>+</sup>, order 7200.
The polyhedral prisms {{CDD|node_1|p|node_1|q|node_1|2|node_1}}, can be alternated into {{CDD|node_h|p|node_h|q|node_h|2x|node_h}}, but do not generate uniform solutions.
# [[Full snub tetrahedral antiprism]], <math>s\left\{\begin{array}{l}3\\3\\2\end{array}\right\}</math> {{CDD|node_h|3|node_h|3|node_h|2x|node_h}}, 2 [[icosahedron]]s connected by 6 [[tetrahedron]]s, and 8 [[octahedron]]s, with 24 tetrahedra in the alternated gaps.
# [[Full snub cubic antiprism]], <math>s\left\{\begin{array}{l}4\\3\\2\end{array}\right\}</math> {{CDD|node_h|4|node_h|3|node_h|2x|node_h}}, 2 [[snub cube]]s connected by 12 [[tetrahedron]]s, 6 [[square antiprism]]s, and 8 [[octahedron]]s, with 48 tetrahedra in the alternated gaps.
# [[Full snub dodecahedral antiprism]], <math>s\left\{\begin{array}{l}5\\3\\2\end{array}\right\}</math> {{CDD|node_h|5|node_h|3|node_h|2x|node_h}}, 2 [[snub dodecahedron]]s connected by 30 [[tetrahedron]]s, 12 [[pentagonal antiprism]]s, and 20 [[octahedron]]s, with 120 tetrahedra in the alternated gaps.
 
The [[duoprism]]s {{CDD|node_1|p|node_1|2|node_1|q|node_1}}, t<sub>0,1,2,3</sub>{p,2,q}, can be alternated into {{CDD|node_h|p|node_h|2x|node_h|q|node_h}}, ht<sub>0,1,2,3</sub>{p,2,q}, called [[duoantiprism]]s, which cannot be made uniform in general. The only convex uniform solution is the trivial case of p=q=2, which is a lower symmetry construction of the [[tesseract]] {{CDD|node_1|2c|node_1|2c|node_1|2c|node_1}}, t<sub>0,1,2,3</sub>{2,2,2} = t{2<sup>1,1,1</sub>}, with its alternation as the [[16-cell]], {{CDD|node_h|2x|node_h|2x|node_h|2x|node_h}}, s{2<sup>1,1,1</sub>} = <math>s\left\{\begin{array}{l}2\\2\\2\end{array}\right\}</math>.
 
=== Geometric derivations for 46 nonprismatic Wythoffian uniform polychora ===<!-- This section is linked from [[Convex uniform honeycomb]] -->
The 46 Wythoffian polychora include the six [[convex regular 4-polytope|convex regular polychora]]. The other forty can be derived from the regular polychora by geometric operations which preserve most or all of their [[symmetry|symmetries]], and therefore may be classified by the [[symmetry group]]s that they have in common.

|}
 
The geometric operations that derive the 40 uniform polychora from the regular polychora are ''truncating'' operations. A polychoron may be truncated at the vertices, edges or faces, leading to addition of cells corresponding to those elements, as shown in the columns of the tables below.
 
The '''[[Coxeter-Dynkin diagram]]''' shows the four mirrors of the Wythoffian kaleidoscope as nodes, and the edges between the nodes are labeled by an integer showing the angle between the mirrors ([[pi|&pi;]]/''n'' [[radian]]s or 180/''n'' degrees). Circled nodes show which mirrors are active for each form; a mirror is active with respect to a vertex that does not lie on it.

See also [[convex uniform honeycomb]]s, some of which illustrate these operations as applied to the regular [[cubic honeycomb]].
 
If two polytopes are [[Dual polytope|dual]]s of each other (such as the tesseract and 16-cell, or the 120-cell and 600-cell), then '''bitruncating''', '''runcinating''' or '''omnitruncating''' either produces the same figure as the same operation to the other.  Thus where only the participle appears in the table it should be understood to apply to either parent.
 
==== Summary of constructions by extended symmetry ====
The 46 uniform polychora constructed from the A<sub>4</sub>, BC<sub>4</sub>, F<sub>4</sub>, H<sub>4</sub> symmetry are given in this table by their full extended symmetry and Coxeter diagrams. Alternations are grouped by their chiral symmetry. All alternations are given, although the [[snub 24-cell]], with its 3 family of constructions is the only one that is uniform. Counts in parenthesis are either repeats or nonuniform. The Coxeter diagrams are given with subscript indices 1 through 46. The 3-3 and 4-4 duoprismatic family is included, the second for its relation to the BC<sub>4</sub> family.

{{main|Polychoric symmetry groups}}
There are 5 fundamental mirror symmetry [[point group]] families in 4-dimensions: '''A'''<sub>4</sub>: {{CDD|node|3|node|3|node|3|node}}, '''BC'''<sub>4</sub>: {{CDD|node|4|node|3|node|3|node}}, '''D'''<sub>4</sub>: {{CDD|node|3|node|split1|nodes}}, '''F'''<sub>4</sub>: {{CDD|node|3|node|4|node|3|node}}, '''H'''<sub>4</sub>: {{CDD|node|5|node|3|node|3|node}}, and I<sub>2</sub>(p)×I<sub>2</sub>(q) as {{CDD|node|p|node|2|node|q|node}}. Each group defined by a [[Goursat tetrahedron#3-sphere (finite) solutions|Goursat tetrahedron]] [[fundamental domain]] bounded by mirror planes.
