Small ditetrahedronary prismatohexacosicubihecatonicosachoron

The small ditetrahedronary prismatohexacosicubihecatonicosachoron, or sadtip xachi, is a nonconvex uniform polychoron that consists of 600 cubes (lying in the same hyperplanes, forming 120 compounds of five cubes), 600 tetrahedra, 720 pentagonal prisms, and 120 small dodecicosidodecahedra. Eight cubes (or four compounds), four tetrahedra, twelve pentagonal 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.
