Small dipentary hexacosidishecatonicosidishecatonicosachoron

The small dipentary hexacosidishecatonicosidishecatonicosachoron, or sidpaxid hidy, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 truncated icosahedra, 600 cuboctahedra, 120 rhombidodecadodecahedra, and 120 small icosicosidodecahedra. One great icosahedron, five truncated icosahedra, five cuboctahedra, five rhombidodecadodecahedra, and five small icosicosidodecahedra join at each vertex.

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