Medial rhombiprismic hecatonicosihecatonicosachoron

The medial rhombiprismic hecatonicosihecatonicosachoron, or marphihy, is a nonconvex uniform polychoron that consists of 120 great rhombidodecahedra, 720 decagonal prisms, and 120 quasitruncated dodecadodecahedra. One great rhombidodecahedron, two decagonal prisms, and two quasitruncated dodecadodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the medial prismatotrishecatonicosachoron.
