Great dipentary trishecatonicosachoron

The great dipentary trishecatonicosachoron, or gidipthi, is a nonconvex uniform polychoron that consists of 120 icosahedra, 120 small stellated dodecahedra, and 120 great dodecicosidodecahedra. 1 icosahedron, 1 small stellated dodecahedron, and 5 great dodecicosidodecahedra join at each vertex.

The vertices of a great dipentary trishecatonicosachoron of edge length 1 are given by all even permutations of:
 * $$\left(0,\,±\frac{1+\sqrt5}{4},\,±\frac12,\,±3\frac{\sqrt5-1}{4}\right),$$
