Small dipentary trishecatonicosidishecatonicosachoron

The small dipentary trishecatonicosidishecatonicosachoron, or sidpathidy, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 great dodecahedra, 120 rhombicosahedra, 120 small dodecicosahedra, and 120 small rhombicosidodecahedra. One great icosahedron, one great dodecahedron, five rhombicosahedra, five small dodecicosahedra, and five small rhombicosidodecahedra join at each vertex.

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