Orthocistransbiblended disnub disoctachoron

The orthocistransbiblended disnub disoctachoron, or octabeb desdo, is a nonconvex uniform polychoron that consists of 8 great icosahedra, 8 icosahedra, 192 tetrahedra, 96+32+32 octahedra, 32+32 tetrahemihexahedra, and 16+16 cuboctahedra. One great icosahedron, one icosahedron, eight tetrahedra, ten 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.

Related polychora
There are other idtessids that it shares blend components with, but that have different facet counts. The first of a similar group of these is the cisorthocisbiblended disnub disoctachoron, and another is the cistransorthobiblended disnub disoctachoron.
