The small dispinosnub snub hexishexacosipentishexacosichoron, or sedansoshexphi, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra and 600 great icosahedra (falling into pairs in the same hyperplanes, forming 600 compounds of one of each), 600 great dodecahedra, 4800 cubohemioctahedra (forming 2400 compounds of two), 600 rhombidodecadodecahedra, 600 small dodecicosahedra, 600 small rhombidodecahedra, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).
One small stellated dodecahedron and one great icosahedron (two compounds), one great dodecahedron, eight cubohemioctahedra (eight compounds), five rhombidodecadodecahedra, five small dodecicosahedra, five small rhombidodecahedra, and five truncated tetrahedra (one compound, four single) join at each vertex.
It can be obtained as the blend of 5 small capped dipentary tetrishecatonicosihexacosichora and 5 small dipentary dishecatonicosidishexacosichora. In the process, some of the cubohemioctahedron cells blend out.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the small diretrosnub disnub decahecatonicosadishexacosichoron.
