Small snubdisnub dishexacosichoron

The small snubdisnub dishexacosichoron, or sisdasadex, is a nonconvex uniform polychoron that consists of 600 icosahedra, 600 small dodecicosidodecahedra, 4800 octahedra (some of which lie in the same hyperplanes, forming 2400 golden hexagrammic antiprisms), and 3600 pentagonal prisms. Two icosahedra, ten small dodecicosidodecahedra, eight octahedra (eight compounds), and ten pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 rox and 5 lifpipixhi. In the process, some of the octahedron cells blend out.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small disnub dishexacosichoron.
