Great diretrosnub prismatodisnub heptishexacosichoron

The great diretrosnub prismatodisnub heptishexacosichoron, or gaderspeedshox, is a nonconvex uniform polychoron that consists of 1200 small stellated dodecahedra (falling into pairs in the same hyperplanes, forming 600 pentagrammatic snub pseudodisoctahedra), 600 icosahedra, 4800 octahemioctahedra (forming 2400 compounds of two), 600 great ditrigonal dodecicosidodecahedra and 600 great dodecicosahedra (forming 600 compounds of one of each), 600 icosidodecadodecahedra, 600 quasirhombicosidodecahedra, and 6000 triangular prisms.

Two small stellated dodecahedra (two compounds), one icosahedron, eight octahemioctahedra (eight compounds), five great ditrigonal dodecicosidodecahedra and five great dodecicosahedra (ten compounds), five icosidodecadodecahedra, five quasirhombicosidodecahedra, and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary trishecatonicosihecatonicosihexacosichora and 5 great dipentary trishecatonicosiprismatohexacosichora. In the process, some of the octahemioctahedron cells blend out.

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