Small dipentary dishecatonicosihexacosidishecatonicosachoron

The small dipentary dishecatonicosihexacosidishecatonicosachoron, or sidpid hixady, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 great dodecahedra, 600 cuboctahedra, 120 rhombidodecadodecahedra, and 120 small ditrigonal dodecicosidodecahedra. One great icosahedron, one great dodecahedron, five cuboctahedra, five rhombidodecadodecahedra, and five small ditrigonal dodecicosidodecahedra join at each vertex.

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