Retroinvertifrustary hecatonicosiprismatotrishecatonicosachoron

The retroinvertifrustary hecatonicosiprismatotrishecatonicosachoron, or rifhipthi, is a nonconvex uniform polychoron that consists of 120 great ditrigonal dodecicosidodecahedra, 120 small rhombicosidodecahedra, 120 small dodecicosahedra, 120 icosidodecatruncated icosidodecahedra, and 1200 hexagonal prisms. Two great ditrigonal dodecicosidodecahedra, two small rhombicosidodecahedra, two small dodecicosahedra, four icosidodecatruncated icosidodecahedra, and four hexagonal prisms join at each vertex.

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