In eight-dimensional geometry, an eight-dimensional polytope or 8-polytope is a polytope contained by 7-polytope facets. Each 6-polytope ridge being shared by exactly two 7-polytope facets.
A uniform 8-polytope is one which is vertex-transitive, and constructed from uniform 7-polytope facets.
Regular 8-polytopes[]
Regular 8-polytopes can be represented by the Schläfli symbol {p,q,r,s,t,u,v}, with v {p,q,r,s,t,u} 7-polytope facets around each peak.
There are exactly three such convex regular 8-polytopes:
- {3,3,3,3,3,3,3} - 8-simplex
- {4,3,3,3,3,3,3} - 8-cube
- {3,3,3,3,3,3,4} - 8-orthoplex
There are no nonconvex regular 8-polytopes.
Characteristics[]
The topology of any given 8-polytope is defined by its Betti numbers and torsion coefficients.[1]
The value of the Euler characteristic used to characterise polyhedra does not generalize usefully to higher dimensions, and is zero for all 8-polytopes, whatever their underlying topology. This inadequacy of the Euler characteristic to reliably distinguish between different topologies in higher dimensions led to the discovery of the more sophisticated Betti numbers.[1]
Similarly, the notion of orientability of a polyhedron is insufficient to characterise the surface twistings of toroidal polytopes, and this led to the use of torsion coefficients.[1]
Uniform 8-polytopes by fundamental Coxeter groups[]
Uniform 8-polytopes with reflective symmetry can be generated by these four Coxeter groups, represented by permutations of rings of the Coxeter-Dynkin diagrams:

The A8 family[]
The A8 family has symmetry of order 362880 (9 factorial).
There are 135 forms based on all permutations of the Coxeter-Dynkin diagrams with one or more rings. (128+8-1 cases) These are all enumerated below. Bowers-style acronym names are given in parentheses for cross-referencing.
See also a list of 8-simplex polytopes for symmetric Coxeter plane graphs of these polytopes.

The E8 family[]
The E8 family has symmetry order 696,729,600.
There are 255 forms based on all permutations of the Coxeter-Dynkin diagrams with one or more rings. Eight forms are shown below, 4 single-ringed, 3 truncations (2 rings), and the final omnitruncation are given below. Bowers-style acronym names are given for cross-referencing.

Regular and uniform honeycombs[]
There are five fundamental affine Coxeter groups that generate regular and uniform tessellations in 7-space:
# | Coxeter group | Coxeter diagram | Forms | |
---|---|---|---|---|
1 | [3[8]] | 29 | ||
2 | [4,35,4] | 135 | ||
3 | [4,34,31,1] | 191 (64 new) | ||
4 | [31,1,33,31,1] | 77 (10 new) | ||
5 | [33,3,1] | 143 |
Regular and uniform tessellations include:
- 29 uniquely ringed forms, including:
- 7-simplex honeycomb: {3[8]}
- 135 uniquely ringed forms, including:
- Regular 7-cube honeycomb: {4,34,4} = {4,34,31,1}, =
- 191 uniquely ringed forms, 127 shared with , and 64 new, including:
- 7-demicube honeycomb: h{4,34,4} = {31,1,34,4}, =
- , [31,1,33,31,1]: 77 unique ring permutations, and 10 are new, the first Coxeter called a quarter 7-cubic honeycomb.
- , , , , , , , , ,
- 143 uniquely ringed forms, including:
- 133 honeycomb: {3,33,3},
- 331 honeycomb: {3,3,3,33,1},
Regular and uniform hyperbolic honeycombs[]
There are no compact hyperbolic Coxeter groups of rank 8, groups that can generate honeycombs with all finite facets, and a finite vertex figure. However, there are 4 paracompact hyperbolic Coxeter groups of rank 8, each generating uniform honeycombs in 7-space as permutations of rings of the Coxeter diagrams.
