Great disnub snub hexishexacosipentishecatonicosachoron

The great disnub snub hexishexacosipentishecatonicosachoron, or gidsoshaxphi, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 600 icosahedra, 4800 cuboctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 600 great rhombidodecahedra, 600 rhombidodecadodecahedra, 600 great ditrigonal dodecicosidodecahedra, 600 truncated great icosahedra, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One great icosahedron, one icosahedron, eight cuboctahedra (eight compounds), five great rhombidodecahedra, five rhombidodecadodecahedra, five great ditrigonal dodecicosidodecahedra, five truncated great icosahedra, and five truncated tetrahedra (one compound and four single) join at each vertex.

It can be obtained as the blend of 5 great dipentary hecatonicosihexacosidishecatonicosachora and 5 great dipentary hecatonicosidishexacosidishecatonicosachora. 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.
