Small ditetrahedronary cubihexacosidishecatonicosachoron

The small ditetrahedronary cubihexacosidishecatonicosachoron, or sadticaxady, is a nonconvex uniform polychoron that consists of 600 cubes, 600 tetrahedra, 120 dodecahedra, and 120 small rhombicosidodecahedra. Eight cubes, four tetrahedra, four dodecahedra, and twelve small rhombicosidodecahedra join at each vertex.

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