Small dipentary trishecatonicosihexacosihecatonicosachoron

The small dipentary trishecatonicosihexacosihecatonicosachoron, or sidpathixhi, is a nonconvex uniform polychoron that consists of 120 icosahedra, 120 truncated icosahedra, 600 cuboctahedra, 120 rhombicosahedra, and 120 small dodecicosidodecahedra. One icosahedron, five truncated icosahedra, five cuboctahedra, five rhombicosahedra, and five small dodecicosidodecahedra join at each vertex.

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