Small ditetrahedronary prismatodishecatonicosihexacosichoron

The small ditetrahedronary prismatodishecatonicosihexacosichoron, or sadtipdohix, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 120 icosidodecahedra, 720 pentagonal prisms, and 120 small rhombidodecahedra. Four tetrahedra, six icosidodecahedra, twelve pentagonal prisms, and twelve small rhombidodecahedra join at each vertex.

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