Grand rhombic prismatohecatonicosachoron

The grand rhombic prismatohecatonicosachoron, or garphi, is a nonconvex uniform polychoron that consists of 120 small rhombidodecahedra and 720 decagonal prisms. Two small rhombidodecahedra and four decagonal prisms join at each vertex.

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