Square cupolic prism

The square cupolic prism, or squacupe, is a CRF segmentochoron (designated K-4.69 on Richard Klitzing's list). It consiss of 2 square cupolas, 4 triangular prisms, 1+4 cubes, and 1 octagonal prism.

As the name suggests, it is a prism based on the square cupola. As such, it is a segmentochoron between two square cupolas. It can also be viewed as a segmentochoron between an octagonal prism and a cube.

Two square cuoplic prisms can be attached to opposite octagonal prismatic cells of the square-octagonal duoprism to produce a small rhombicuboctahedral prism.

Vertex coordinates
Coordinates of the vertices of a square cupolic prism of edge length 1 centered at the origin are given by:
 * (±1/2, ±1/2, $\sqrt{2}$/2, ±1/2),
 * (±(1+$\sqrt{2}$)/2, ±1/2, 0, ±1/2),
 * (±1/2, ±(1+$\sqrt{2}$)/2, 0, ±1/2).
