Small rhombicuboctahedral prism

The small rhombicuboctahedral prism or sircope is one of the uniform polychora made as the prism product of a uniform polyhedron and a dyad that consists of 2 small rhombicuboctahedra, 18 cubes of two kinds and 8 triangular prisms.

The small rhombicuboctahedral prism can be vertex-inscribed into a small disprismatotesseractihexadecachoron.

Vertex coordinates
The vertices of a small rhombicuboctahedral prism of edge length 1 are given by all permutations and sign changes of the first three coordinates of:
 * (1/2, 1/2, (1+$\sqrt{2}$)/2, ±1/2)
