Cube atop small rhombicuboctahedron

Cube atop small rhombicuboctahedron, or cubasirco, is a CRF segmentochoron (designated K-4.71 on Richard Klitzing's list). As the name suggests, it consists of a cube and a small rhombicuboctahedron as bases, connected by 8 tetrahedra, 12 triangular prisms, and 6 further cubes.

It is also sometimes referred to as a cubic cupola, as one generalization of the definition of a cupola is to have a polytope atop an expanded version.

A small disprismatotesseractihexadecachoron can be formed by attaching cube atop small rhombicuboctahedron segmentochora to the bases of the small rhombicuboctahedral prism.

Vertex coordinates
Coordinates for the vertices of a cube atop small rhombicuboctahedron of edge length 1 are given by: along with all permutations of the first three coordinates of:
 * (±1/2, ±1/2, ±1/2, $\sqrt{2}$/2),
 * (±(1+$\sqrt{2}$)/2, ±1/2, ±1/2, 0).
