Small retrofrustary prismatodishecatonicosachoron

The small retrofrustary prismatodishecatonicosachoron, or sirfipady, is a nonconvex uniform polychoron that consists of 120 quasirhombicosidodecahedra, 120 small icosicosidodecahedra, and 1200 hexagonal prisms. Two quasirhombicosidodecahedra, two small icosicosidodecahedra, and four hexagonal prisms join at each vertex.

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