Great rhombic hecatonicosihecatonicosachoron

The great rhombic hecatonicosihecatonicosachoron, or girhihy, is a nonconvex uniform polychoron that consists of 120 quasitruncated small stellated dodecahedra, 120 great rhombidodecahedra, and 720 pentagonal prisms. Two quasitruncated small stellated dodecahedra, two great rhombidodecahedra, and two pentagonal prisms join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the sphenoverted trishecatonicosachoron.
