Medial retrofrustary pentishecatonicosachoron

The medial retrofrustary pentishecatonicosachoron, or mirfophi, is a nonconvex uniform polychoron that consists of 120 great icosicosidodecahedra, 120 great dodecicosidodecahedra, 120 small icosicosidodecahedra, 120 small dodecicosidodecahedra, and 120 icosidodecatruncated icosidodecahedra. Two great icosicosidodecahedra, two great dodecicosidodecahedra, two small icosicosidodecahedra, two small dodecicosidodecahedra, and four icosidodecatruncated icosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the antifrustary hexacositrishecatonicosachoron.
