Small ditetrahedronary cubiprismatohecatonicosachoron

The small ditetrahedronary cubiprismatohecatonicosachoron, or sidtacphi, is a nonconvex uniform polychoron that consists of 600 cubes (lying in the same hyperplanes, forming 120 compounds of five cubes), 120 dodecahedra, and 720 pentagonal prisms. Eight cubes (or four compounds), four dodecahedra, and twelve pentagonal prisms join at each vertex.
