Small prismatohexadecadisoctachoron

The small prismatohexadecadisoctachoron, or siphado, is a nonconvex uniform polychoron that consists of 32 triangular prisms, 16 octahemioctahedra, 8 truncated cubes, and 8 great rhombicuboctahedra. 1 triangular prism, 1 truncated cube, 1 octahemioctahedron, and 2 great rhombicuboctahedra join at each vertex.

3 copies of this polychoron can blend to form the small pseudorhombic disicositetrachoron, with the octahemioctahedron cells blending out.

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