The small dispinosnub prismatosnub hexishexacosichoron, or sednaspishax, is a nonconvex uniform polychoron that consists of 1200 small stellated dodecahedra (some of which lie in the same hyperplanes, forming 600 pentagrammatic snub pseudodisoctahedra), 600 great dodecahedra, 4800 cubohemioctahedra (forming 2400 compounds of two), 600 rhombidodecadodecahedra, 1200 small dodecicosahedra (forming 600 compounds of two), and 3600 pentagrammic prisms.
Two small stellated dodecahedra (two compounds), one great dodecahedron, eight cubohemioctahedra (eight compounds), five rhombidodecadodecahedra, ten small dodecicosahedra (ten compounds), and five pentagrammic prisms join at each vertex.
It can be obtained as the blend of 5 small capped dipentary tetrishecatonicosihexacosichora and 5 small dipentary hecatonicosiprismatohecatonicosihexacosichora. 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.
