# Cisretroblended disnub triacontadiadisoctachoron

The **cisretroblended disnub triacontadiadisoctachoron**, or **crab dastedo**, is a nonconvex uniform polychoron that consists of 8 great icosahedra, 8 icosahedra, 192 tetrahedra, 96+32 octahedra, 32 tetrahemihexahedra, 16 octahemioctahedra, and 16 cubohemioctahedra. One great icosahedron, one icosahedron, eight tetrahedra, eight octahedra, two tetrahemihexahedra, two octahemioctahedra, and four cubohemioctahedra join at each vertex.

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

## Vertex coordinatesEdit

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

## Related polychoraEdit

The blend components and facet counts of the cisretroblended disnub triacontadiadisoctachoron are the same as those of the transretroblended disnub triacontadiadisoctachoron, differing only in orientation.
