Small ditetrahedronary cubiprismatodishecatonicosachoron

The small ditetrahedronary cubiprismatodishecatonicosachoron, or sidtacpady, is a nonconvex uniform polychoron that consists of 600 cubes, 120 dodecahedra, 1200 triangular prisms, and 120 small dodecicosidodecahedra. Eight cubes, four dodecahedra, twelve triangular prisms, and twelve small dodecicosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small ditetrahedronary hexacosihecatonicosachoron.
