Truncated great grand hecatonicosachoron

The truncated great grand hecatonicosachoron, or tigaghi, is a nonconvex uniform polychoron that consists of 120 great stellated dodecahedra and 120 truncated great dodecahedra. One great stellated dodecahedron and three truncated great dodecahedra join at each vertex. As the name suggests, it can be obtained by truncating the great grand hecatonicosachoron.

Vertex coordinates
The vertices of a truncated great grand hecatonicosachoron of edge length 1 are all permutations of: along with the even permutations of:
 * $$\left(±\frac{3-\sqrt5}{4},\,±\frac{3-\sqrt5}{4},\,±\frac{1+\sqrt5}{4},\,±\frac{5+\sqrt5}{4}\right),$$
