Great dipentary prismatodishexacosidishecatonicosachoron

The great dipentary prismatodishexacosidishecatonicosachoron, or gidpip dixady, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 icosahedra, 1200 triangular prisms, 600 truncated tetrahedra, and 600 cubohemioctahedra. One great icosahedron, one icosahedron, five triangular prisms, five truncated tetrahedra, and five cubohemioctahedra join at each vertex.

It has the same cell counts as its conjugate, the small dipentary prismatodishexacosidishecatonicosachoron, but the icosahedra and great icosahedra are in opposite positions.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great dipentary trishecatonicosachoron.
