The prismatorhombated great hecatonicosachoron, or pirghi, is a nonconvex uniform polychoron that consists of 720 pentagonal prisms, 720 decagonal prisms, 120 truncated great dodecahedra, and 120 rhombidodecadodecahedra. 1 pentagonal prism, 2 decagonal prisms, 1 truncated great dodecahedron, and 1 rhombidodecadodecahedron join at each vertex. It can be obtained by runcitruncating the great hecatonicosachoron.
The vertices of a prismatorhombated great hecatonicosachoron of edge length 1 are given by all permutations of:

The prismatorhombated great hecatonicosachoron is the colonel of a three-member regiment that also includes the small prismatohecatonicosidishecatonicosachoron and the small rhombiprismic hecatonicosihecatonicosachoron.
