The small diretrosnub heptishexacosichoron, or sedroshox, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 600 great dodecahedra and 600 icosahedra (some of which lie in the same hyperplanes, forming 600 compounds of one of each), 4800 octahemioctahedra (forming 2400 compounds of two), 600 icosidodecadodecahedra, 600 small ditrigonal dodecicosidodecahedra, 600 small dodecicosidodecahedra, and 600 truncated icosahedra.
One great icosahedron, one great dodecahedron and one icosahedron (two compounds), eight octahemioctahedra (eight compounds), five icosidodecadodecahedra, five small ditrigonal dodecicosidodecahedra, five small dodecicosidodecahedra, and five truncated icosahedra join at each vertex.
It can be obtained as the blend of 5 small dipentary trishecatonicosihecatonicosihexacosichora and 5 small invertidipentary hecatonicosihexacosidishecatonicosachora.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the small diretrosnub disnub decahecatonicosadishexacosichoron.
