Orthographic projections in the B₇ Coxeter plane

7-cube

7-orthoplex

7-demicube

In 7-dimensional geometry, there are 128 uniform polytopes with B₇ symmetry. There are two regular forms, the 7-orthoplex, and 8-cube with 14 and 128 vertices respectively. The 7-demicube is added with half of the symmetry.

They can be visualized as symmetric orthographic projections in Coxeter planes of the B₇ Coxeter group, and other subgroups.

Graphs

Symmetric orthographic projections of these 128 polytopes can be made in the B₇, B₆, B₅, B₄, B₃, B₂, A₅, A₃, Coxeter planes. A_k has [k+1] symmetry, and B_k has [2k] symmetry.

These 128 polytopes are each shown in these 8 symmetry planes, with vertices and edges drawn, and vertices colored by the number of overlapping vertices in each projective position.
