Small disnub hexacosihexacosihexacosichoron

The small disnub hexacosihexacosihexacosichoron, or sidsaxixox, is a nonconvex uniform polychoron that consists of 600 great dodecahedra, 600 truncated dodecahedra, 600 small rhombicosidodecahedra, and 4800 octahedra (some of which lie in the same hyperplanes, forming 2400 golden hexagrammic antiprisms). Two great dodecahedra, ten truncated dodecahedra, ten small rhombicosidodecahedra, and eight octahedra (eight compounds) join at each vertex.

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