Great dipentary hecatonicosihexacosidishecatonicosachoron

The great dipentary hecatonicosihexacosidishecatonicosachoron, or gidphixady, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 icosahedra, 600 cuboctahedra, and 120 great rhombidodecahedra. One great icosahedron, one icosahedron, five cuboctahedra, and five great rhombidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great dipentary trishecatonicosachoron.
