Great retrofrustary hexacosidishecatonicosachoron

The great retrofrustary hexacosidishecatonicosachoron, or girfixady, is a nonconvex uniform polychoron that consists of 120 quasirhombicosidodecahedra, 120 small icosicosidodecahedra, and 600 truncated octahedra. Two quasirhombicosidodecahedra, two small icosicosidodecahedra, and four truncated octahedra join at each vertex.

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