Small dipentary prismatohexacositetrishecatonicosachoron

The small dipentary prismatohexacositetrishecatonicosachoron, or siddip puxthi, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 great dodecahedra, 720 pentagrammic prisms, 120 truncated icosahedra, 600 cuboctahedra, and 120 small icosicosidodecahedra. One great icosahedron, one great dodecahedron, five pentagrammic prisms, five truncated icosahedra, five cuboctahedra, and five small icosicosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the prismatodishecatonicosachoron.
