Small rhombiprismic disoctachoron

The small rhombiprismic disoctachoron, or sirpdo, is a nonconvex uniform polychoron that consists of 8 small rhombihexahedra, 8 great rhombicuboctahedra, and 32 hexagonal prisms. One small rhombihexahedron, two great rhombicuboctahedra, and two hexagonal prisms join at each vertex.

It can be constructed as a blend of a compound of four great rhombicuboctahedral prisms.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the prismatorhombated tesseract.
