Small disnub hexacosihexacosichoron

The small disnub hexacosihexacosichoron, or sidsoxix, is a nonconvex uniform polychoron that consists of 600 icosahedra, 600 truncated dodecahedra, and 4800 octahedra (which form 2400 golden hexagrammic antiprisms). Two icosahedra, ten truncated dodecahedra, and eight octahedra (eight compounds) join at each vertex.

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