Small retroditetrahedronary hecatonicosiprismatodishecatonicosachoron

The small retroditetrahedronary hecatonicosiprismatodishecatonicosachoron, or sard thipady, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 120 icosidodecahedra, 1200 triangular prisms, and 120 small rhombidodecahedra. Four ditrigonary dodecadodecahedra, six icosidodecahedra, twelve triangular 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.
