Small based dipentary trishecatonicosiprismatohexacosichoron

The small based dipentary trishecatonicosiprismatohexacosichoron, or sibdip thipix, is a nonconvex uniform polychoron that consists of 120 icosahedra, 720 pentagrammic prisms, 600 octahemioctahedra, 120 icosidodecadodecahedra, and 120 small rhombicosidodecahedra. One icosahedron, five pentagrammic prisms, five octahemioctahedra, five icosidodecadodecahedra, and five small rhombicosidodecahedra join at each vertex.

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