Pseudorhombic dishecatonicosachoron

The pseudorhombic dishecatonicosachoron, or pirdy, is a nonconvex uniform polychoron that consists of 120 truncated great dodecahedra, 720 pentagrammic prisms, and 120 quasitruncated dodecadodecahedra. Two truncated great dodecahedra, two pentagrammic prisms, 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.
