Orthogonal projections in A4 Coxeter plane

In four-dimensional geometry, a runcinated 5-cell is a convex uniform 4-polytope, being a runcination (a 3rd order truncation, up to face-planing) of the regular 5-cell.

There are 3 unique degrees of runcinations of the 5-cell, including with permutations, truncations, and cantellations.
