Invertipental hexacosidishecatonicosachoron

The invertopental hexacosidishecatonicosachoron, or ipixady, is a nonconvex uniform polychoron that consists of 120 great dodecahedra, 120 small dodecicosidodecahedra, and 600 octahedra.

It is superficially identical to the intercepted invertopental hexacosidishecatonicosachoron, differing only internally.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the rectified hexacosichoron.
