Pseudorhombic hecatonicosihecatonicosachoron

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

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