In nine-dimensional geometry, a polyyotton (or 9-polytope) is a polytope contained by 8-polytope facets. Each 7-polytope ridge being shared by exactly two 8-polytope facets.

A uniform polyyotton is one which is vertex-transitive, and constructed from uniform facets.

A proposed name for 9-polytope is polyyotton (plural: polyyotta), created from poly-, yotta- (a variation on octa, meaning eight) and -on.

Regular 9-polytopes

Regular 9-polytopes can be represented by the Schläfli symbol {p,q,r,s,t,u,v,w}, with w {p,q,r,s,t,u,v} 8-polytope facets around each peak.

There are exactly three such convex regular 9-polytopes:

{3,3,3,3,3,3,3,3} - 9-simplex
{4,3,3,3,3,3,3,3} - 9-cube
{3,3,3,3,3,3,3,4} - 9-orthoplex

There are no nonconvex regular 9-polytopes.

Euler characteristic

The Euler characteristic for 9-polytopes that are topological 8-spheres (including all convex 9-polytopes) is zero. χ=V-E+F-C+f₄-f₅+f₆-f₇+f₈=2.

Uniform 9-polytopes by fundamental Coxeter groups

Uniform 9-polytopes with reflective symmetry can be generated by these three Coxeter groups, represented by permutations of rings of the Coxeter-Dynkin diagrams:

Coxeter group		Coxeter-Dynkin diagram
A₉	[3⁸]	Template:CDD
B₉	[4,3⁷]	Template:CDD
D₉	[3^6,1,1]	Template:CDD

Selected regular and uniform 9-polytopes from each family include:

Simplex family: A₉ [3⁸] - Template:CDD
- 271 uniform 9-polytopes as permutations of rings in the group diagram, including one regular:
  1. {3⁸} - 9-simplex or deca-9-tope or decayotton - Template:CDD
Hypercube/orthoplex family: B₉ [4,3⁸] - Template:CDD
- 511 uniform 9-polytopes as permutations of rings in the group diagram, including two regular ones:
  1. {4,3⁷} - 9-cube or enneract - Template:CDD
  2. {3⁷,4} - 9-orthoplex or enneacross - Template:CDD
Demihypercube D₉ family: [3^6,1,1] - Template:CDD
- 383 uniform 9-polytope as permutations of rings in the group diagram, including:
  1. {3^1,6,1} - 9-demicube or demienneract, 1_6,1 - Template:CDD; also as h{4,3⁸} Template:CDD.
  2. {3^6,1,1} - 9-orthoplex, 6_1,1 - Template:CDD

The A₉ family

The A₉ family has symmetry of order 3628800 (10 factorial).

There are 256+16-1=271 forms based on all permutations of the Coxeter-Dynkin diagrams with one or more rings. These are all enumerated below. Bowers-style acronym names are given in parentheses for cross-referencing.

There are 511 forms based on all permutations of the Coxeter-Dynkin diagrams with one or more rings.

Eleven cases are shown below: Nine rectified forms and 2 truncations. Bowers-style acronym names are given in parentheses for cross-referencing. Bowers-style acronym names are given in parentheses for cross-referencing.

The D₉ family

The D₉ family has symmetry of order 92,897,280 (9 factorial × 2⁸).

This family has 3×128−1=383 Wythoffian uniform polytopes, generated by marking one or more nodes of the D₉ Coxeter-Dynkin diagram. Of these, 255 (2×128−1) are repeated from the B₉ family and 128 are unique to this family, with the eight 1 or 2 ringed forms listed below. Bowers-style acronym names are given in parentheses for cross-referencing.

Regular and uniform honeycombs

Coxeter-Dynkin diagram correspondences between families and higher symmetry within diagrams. Nodes of the same color in each row represent identical mirrors. Black nodes are not active in the correspondence.

There are five fundamental affine Coxeter groups that generate regular and uniform tessellations in 8-space:

#	Coxeter group		Coxeter diagram	Forms
1	${\tilde{A}}_{8}$	[3^[9]]	Template:CDD	45
2	${\tilde{C}}_{8}$	[4,3⁶,4]	Template:CDD	271
3	${\tilde{B}}_{8}$	h[4,3⁶,4] [4,3⁵,3^1,1]	Template:CDD	383 (128 new)
4	${\tilde{D}}_{8}$	q[4,3⁶,4] [3^1,1,3⁴,3^1,1]	Template:CDD	155 (15 new)
5	${\tilde{E}}_{8}$	[3^5,2,1]	Template:CDD	511

Regular and uniform tessellations include:

A~8 45 uniquely ringed forms
- 8-simplex honeycomb: {3^[9]} Template:CDD
C~8 271 uniquely ringed forms
- Regular 8-cube honeycomb: {4,3⁶,4}, Template:CDD
B~8: 383 uniquely ringed forms, 255 shared with C~8, 128 new
- 8-demicube honeycomb: h{4,3⁶,4} or {3^1,1,3⁵,4}, Template:CDD or Template:CDD
${\tilde{D}}_{8}$ , [3^1,1,3⁴,3^1,1]: 155 unique ring permutations, and 15 are new, the first, Template:CDD, Coxeter called a quarter 8-cubic honeycomb, representing as q{4,3⁶,4}, or qδ₉.
E~8 511 forms

Regular and uniform hyperbolic honeycombs

There are no compact hyperbolic Coxeter groups of rank 9, groups that can generate honeycombs with all finite facets, and a finite vertex figure. However there are 4 noncompact hyperbolic Coxeter groups of rank 9, each generating uniform honeycombs in 8-space as permutations of rings of the Coxeter diagrams.

${\bar{P}}_{8}$ = [3,3^[8]]: Template:CDD	${\bar{Q}}_{8}$ = [3^1,1,3³,3^2,1]: Template:CDD	${\bar{S}}_{8}$ = [4,3⁴,3^2,1]: Template:CDD	${\bar{T}}_{8}$ = [3^4,3,1]: Template:CDD
