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

Vertex coordinates

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