Medial invertifrustary pentishecatonicosachoron

The medial invertifrustary pentishecatonicosachoron, or miffophi, is a nonconvex uniform polychoron that consists of 120 great icosicosidodecahedra, 120 great rhombidodecahedra, 120 small dodecicosahedra, 120 small rhombicosidodecahedra, and 120 icosidodecatruncated icosidodecahedra. Two great icosicosidodecahedra, two great rhombidodecahedra, two small dodecicosahedra, two small rhombicosidodecahedra, and four icosidodecatruncated icosidodecahedra join at each vertex.

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