Small disnub hexacosidishexacosichoron

The small disnub hexacosidishexacosichoron, or sidsaxadox, is a nonconvex uniform polychoron that consists of 600 icosahedra and 600 great dodecahedra (some of which lie in the same hyperplanes, forming 600 compounds of one of each of them), 600 small dodecicosidodecahedra, and 4800 octahedra (which form 2400 golden hexagrammic antiprisms). Two icosahedra and two truncated dodecahedra (two compounds), ten small dodecicosidodecahedra, and eight octahedra (eight compounds) join at each vertex.

It can be obtained as the blend of 5 rox and 5 ipixady. 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.
