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:

1. {3,3,3,3,3,3,3} - 8-simplex
2. {4,3,3,3,3,3,3} - 8-cube
3. {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.

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.

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.

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:

#	Coxeter group			Forms
1	A8	[37]		135
2	BC8	[4,36]		255
3	D8	[35,1,1]		191 (64 unique)
4	E8	[34,2,1]		255

Selected regular and uniform 8-polytopes from each family include:

1. Simplex family: A₈ [3⁷] -

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.

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

File:Coxeter diagram affine rank8 correspondence.png

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 7-space:

#	Coxeter group		Coxeter diagram	Forms
1	${\tilde{A}}_7$	[3[8]]		29
2	${\tilde{C}}_7$	[4,35,4]		135
3	${\tilde{B}}_7$	[4,34,31,1]		191 (64 new)
4	${\tilde{D}}_7$	[31,1,33,31,1]		77 (10 new)
5	${\tilde{E}}_7$	[33,3,1]		143

Regular and uniform tessellations include:

• ${\tilde{A}}_7$ 29 uniquely ringed forms, including:
  • 7-simplex honeycomb: {3^[8]}
• ${\tilde{C}}_7$ 135 uniquely ringed forms, including:
  • Regular 7-cube honeycomb: {4,3⁴,4} = {4,3⁴,3^1,1}, =
• ${\tilde{B}}_7$ 191 uniquely ringed forms, 127 shared with ${\tilde{C}}_7$, and 64 new, including:
  • 7-demicube honeycomb: h{4,3⁴,4} = {3^1,1,3⁴,4}, =
• ${\tilde{D}}_7$, [3^1,1,3³,3^1,1]: 77 unique ring permutations, and 10 are new, the first Coxeter called a quarter 7-cubic honeycomb.
  • , , , , , , , , ,
• ${\tilde{E}}_7$ 143 uniquely ringed forms, including:
  • 1₃₃ honeycomb: {3,3^3,3},
  • 3₃₁ honeycomb: {3,3,3,3^3,1},

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 noncompact hyperbolic Coxeter groups of rank 8, each generating uniform honeycombs in 7-space as permutations of rings of the Coxeter diagrams.
