Great retrospinosnub prismatosnub dishexacositetrishexacosichoron

The great retrospinosnub prismatosnub dishexacositetrishexacosichoron, or garnsips dextux, is a nonconvex uniform polychoron that consists of 600 great icosahedra and 600 small stellated dodecahedra (falling into pairs in the same hyperplanes, forming 600 compounds of one of each), 600 great dodecahedra, 2400 octahemioctahedra and 2400 cubohemioctahedra (forming 2400 compounds of one of each), 600 cuboctahedra (forming 120 antirhombicosicosahedra), 1200 truncated great icosahedra (forming 600 compounds of two), 600 great dodecicosidodecahedra, and 3600 pentagonal prisms.

One great icosahedron and one small stellated dodecahedron (two compounds), one great dodecahedron, four octahemioctahedra and four cubohemioctahedra (eight compounds), one cuboctahedron (one compound), ten truncated great icosahedra (ten compounds), five great dodecicosidodecahedra, and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great invertidipentary hecatonicosihexacosidishecatonicosachora and 5 great capped dipentary prismatohexacositrishecatonicosachora. In the process, some of the octahemioctahedron and cubohemioctahedron cells blend out.

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