Great skewverted prismatoprismatodishecatonicosachoron

The Great skewverted prismatoprismatodishecatonicosachoron, or gikkiv pappady, is a nonconvex uniform polychoron that consists of 120 rhombicosahedra, 120 small rhombidodecahedra, 720 decagonal prisms, and 1200 hexagonal prisms. One rhombicosahedron, one small rhombidodecahedron, two decagonal prisms, and two hexagonal prisms join at each vertex.
