Small dipentary hecatonicositetrishecatonicosachoron

The small dipentary hecatonicositetrishecatonicosachoron, or sidphiuthi, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra, 120 icosahedra, 120 rhombicosahedra, 120 small rhombidodecahedra, and 120 small icosicosidodecahedra. One small stellated dodecahedron, one icosahedron, five rhombicosahedra, five small rhombidodecahedra, and five small icosicosidodecahedra join at each vertex.

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