Rectified hecatonicosachoron

The rectified hecatonicosachoron, or rahi, also commonly called the rectified 120-cell, is a convex uniform polychoron that consists of 600 regular tetrahedra and 120 icosidodecahedra. Two tetrahedra and three icosidodecahedra join at each triangular prismatic vertex. As the name suggests, it can be obtained by rectifying the hecatonicosachoron.

Vertex coordinates
The vertices of a rectified hecatonicosachoron of edge length 1 are given by all permutations of: along with all even permutations of:
