Great snubspinosnub prismatodisnub pentishexacosichoron

The great snubspinosnub prismatodisnub pentishexacosichoron, or gosenspidspox, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra and 600 great dodecahedra (some of which lie in the same hyperplanes, forming 600 compounds of one of each), 2400 cuboctahedra and 2400 cubohemioctahedra (forming 2400 compounds of one of each), 600 octahemioctahedra (forming 120 icosidisicosahedra), 600 rhombidodecadodecahedra, 600 great dodecicosahedra, and 6000 triangular prisms.

One small stellated dodecahedron, one icosahedron and one great dodecahedron (two compounds), four cuboctahedra and four cubohemioctahedra (eight compounds), one octahemioctahedron (one compound), five rhombidodecadodecahedra, five great dodecicosahedra, and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary prismatohexacosihecatonicosachora and 5 great capped dipentary tetrishecatonicosihexacosichora. In the process, some of the cuboctahedron and cubohemioctahedron cells blend out.

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