Cisorthotransbiblended disnub disoctachoron

The cisorthotransbiblended disnub disoctachoron, or cotebab desdo, is a nonconvex uniform polychoron that consists of 8 great icosahedra, 8 icosahedra, 192 tetrahedra, 96+32 octahedra, 32+32 tetrahemihexahedra, and 16+16 cuboctahedra. One great icosahedron, one icosahedron, eight tetrahedra, eight octahedra, four tetrahemihexahedra, and four cuboctahedra join at each vertex.

It can be obtained as the blend of a snub hexecontatetrasnub-snub disoctachoron and 8 rectified tesseractihemioctachora. 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.

The blend components and facet counts of the cisorthotransbiblended disnub disoctachoron are the same as those of three other idtessids, differing only in orientation. Those are the:
 * cisorthocisbiblended disnub disoctachoron,
 * transorthocisbiblended disnub disoctachoron,
 * transorthotransbiblended disnub disoctachoron.

There are other idtessids that it shares blend components with, but that have different facet counts. Those are the:
 * cistransorthobiblended disnub disoctachoron,
 * orthocistransbiblended disnub disoctachoron.
