In [[Four-dimensional space|four-dimensional]] [[Euclidean geometry]], the '''omnitruncated 4-simplex honeycomb''' or '''omnitruncated 5-cell honeycomb''' is a space-filling [[tessellation]] [[honeycomb (geometry)|honeycomb]]. It is composed entirely of [[omnitruncated 5-cell]] (omnitruncated 4-simplex) facets.
 
[[Coxeter]] calls this '''Hinton's honeycomb''' after [[Charles Howard Hinton|C. H. Hinton]],  who described it in his book ''The Fourth Dimension'' in 1906.<ref name=cox>{{cite book|title=The Beauty of Geometry: Twelve Essays|year= 1999|publisher= Dover Publications|lccn=99035678|isbn= 0-486-40919-8 }} (The classification of Zonohededra, page 73)</ref>
 
The facets of all  [[omnitruncated simplectic honeycomb]]s are called [[permutahedron|permutahedra]] and can be positioned in ''n+1'' space with integral coordinates, permutations of the whole numbers (0,1,..,n).

The A{{sup sub|*|4}} lattice is the union of five A<sub>4</sub> lattices, and is the dual to the [[omnitruncated 5-simplex honeycomb]], and therefore the [[Voronoi cell]] of this lattice is an [[omnitruncated 5-cell]]
