Great pseudorhombic hecatonicosihecatonicosachoron

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

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