Grand rhombic hecatonicosihecatonicosachoron

The grand rhombic hecatonicosihecatonicosachoron, or garhihy, is a nonconvex uniform polychoron that consists of 120 small rhombidodecahedra and 120 quasitruncated dodecadodecahedra. Two small rhombidodecahedra and four quasitruncated dodecadodecahedra join at each vertex.

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