Small pseudorhombic hecatonicosihecatonicosachoron

The small pseudorhombic hecatonicosihecatonicosachoron, or sprahihy, is a nonconvex uniform polychoron that consists of 120 truncated great dodecahedra, 720 pentagrammic prisms, and 120 great rhombicosidodecahedra. Two truncated great dodecahedra, two pentagrammic prisms, and four great rhombicosidodecahedra join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small rhombated faceted hexacosichoron.
