Square-great rhombicuboctahedral duoprism

The square-great rhombicuboctahedral duoprism or squagirco is a convex uniform duoprism that consists of 4 great rhombicuboctahedral prisms, 6 square-octagonal duoprisms, 12 tesseracts and 8 square-hexagonal duoprisms.

The square-great rhombicuboctahedral duoprism can be vertex-inscribed into a celliprismated penteract.

This polyteron can be alternated into a digonal-snub cubic duoantiprism, although it cannot be made uniform. The great rhombicuboctahedra can also be edge-snubbed to create a digonal-pyritohedral prismantiprismoid, which is also nonuniform.

Vertex coordinates
The vertices of a square-great rhombicuboctahedral duoprism of edge length 1 are given by all permutations and sign changes of the last three coordinates of:
 * (±1/2, ±1/2, ±1/2, ±(1+$\sqrt{15+6√2}$)/2, ±(1+2$\sqrt{2}$)/2)
