D8 polytope
Uniform polytopes with D₈ symmetry
In 8-dimensional geometry, there are 191 uniform polytopes with D8 symmetry, 64 are unique, and 127 are shared with the B8 symmetry. There are two regular forms, the 8-orthoplex, and 8-demicube with 16 and 128 vertices respectively.
8-demicube = |
8-orthoplex = |
They can be visualized as symmetric orthographic projections in Coxeter planes of the D8 Coxeter group, and other subgroups.
