Small hexadecafaceted prismatotesseractioctachoron

The small hexadecafaceted prismatotesseractioctachoron, or shafipto, is a nonconvex uniform polychoron that consists of 8 cubes, 32 triangular prisms, and 8 small rhombicuboctahedra. One cube, three triangular prisms, and three small rhombicuboctahedra join at each vertex.

It also has 16 tetrahedra and 24 cubes as pseudofacets.

It can be constructed as a blend of four small rhombicuboctahedral prisms. In the process some of the cubical cells blend out. Alternatively, it can be thought of as a blend of four small cubicuboctahedral prisms. In the process the octagonal prism side cells blend with the base small cubicuboctahedra to produce the small rhombicuboctahedra.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small disprismatotesseractihexadecachoron.
