The square biantiprismic ring is a member of the infinite family of biantiprismic rings, which are 4D CRF polychora. It consists of a 3-membered ring containing two square antiprisms and a cube, flanked by a circle of 4 tetrahedra and 4 square pyramids.
Cartesian coordinates
Cube:
(±1, ±1, ±1, 0)
Square:
(±sqrt(2), 0, 0, H) (0, ±sqrt(2), 0, H)
where H = sqrt(2*sqrt(2) - 1).
