Polytope of the Month

This month, we return to 4D:

This is the bidecachoron, the dual of the bitruncated 5-cell. It is bounded by 30 congruent tetragonal disphenoids, 60 congruent isosceles triangles, 40 edges, and 10 vertices.

Find out more in the bidecachoron page! As usual, full algebraic coordinates are provided.
