Retrodishexadecateron

The retrodishexadecateron or radah is a uniform polyteron composed of 16 pentachora and 16 facetorectified pentachora. 5 pentachora and 10 facetorectified pentachora meet at a vertex.

Vertex coordinates
The vertex coordinates of a retrodishexadecateron are given by all even sign changes of:
