Retroblended disnub triacontadiadisoctachoron

The retroblended disnub triacontadiadisoctachoron, or rob destido, is a nonconvex uniform polychoron that consists of 8 great icosahedra, 8 icosahedra, 192 tetrahedra, 96+32 octahedra, and 32 octahemioctahedra. One great icosahedron, one icosahedron, eight tetrahedra, eight octahedra, and four octahemioctahedra join at each vertex.

It can be obtained as the blend of a snub hexecontatetrasnub-snub disoctachoron and 4 octahemihexadecachora. In the process, some of the octahedron cells blend out.

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