Pseudorhombic great hecatonicosihexacosichoron

The pseudorhombic great hecatonicosihexacosichoron, or pirghix, is a nonconvex uniform polychoron that consists of 120 truncated great icosahedra, 720 pentagrammic prisms, and 600 truncated octahedra. Two truncated great icosahedra, two pentagrammic prisms, and four truncated octahedra join at each vertex.

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