Small ditetrahedronary prismatodishecatonicosachoron

The small ditetrahedronary prismatodishecatonicosachoron, or sidtapady, is a nonconvex uniform polychoron that consists of 120 dodecahedra, 720 pentagonal prisms, and 120 small rhombidodecahedra. Four dodecahedra, 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.
