Small dipentary tetrishecatonicosiprismatohexacosichoron

The small dipentary tetrishecatonicosiprismatohexacosichoron, or siddip thipox, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra, 120 icosahedra, 720 pentagrammic prisms, 120 truncated icosahedra, 600 octahemioctahedra, and 120 small rhombicosidodecahedra. One small stellated dodecahedron, one icosahedron, five pentagrammic prisms, five truncated icosahedra, five octahemioctahedra, and five small rhombicosidodecahedra join at each vertex.

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