Great disnub snub prismatosnub pentishexacosipentishecatonicosachoron

The great disnub snub prismatosnub pentishexacosipentishecatonicosachoron, or gidsospas pixphi, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra, 4800 cuboctahedra (in pairs in the same hyperplane, forming 2400 compounds of 2), 600 rhombidodecadodecahedra, 600 great ditrigonal dodecicosidodecahedra and 600 great icosicosidodecahedra (one of each in the same hyperplane, forming 600 compounds), 3600 pentagonal prisms, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One small stellated dodecahedron, one icosahedron, eight cuboctahedra, five rhombidodecadodecahedra, five great ditrigonal dodecicosidodecahedra, five great icosicosidodecahedra, five pentagonal prisms, and five truncated tetrahedra (one compound and four single) join at each vertex.

It can be obtained as the blend of 5 great dipentary hexacosiprismatodishecatonicosachora and 5 great dipentary hecatonicosihexacosidishecatonicosihexacosichora. In the process, some of the cuboctahedron cells blend out.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great diretrosnub disnub decahecatonicosadishexacosichoron.
