The square orthobicupolic ring is a CRF polychoron discovered by Keiji. It is a member of the family of bicupolic rings, which contains eight other similar polychora. It is formed by attaching two square cupolae by their octagonal faces, folding them into the fourth dimension with their square ends connected by a cube, and then filling in the gaps with 4 triangular prisms and 4 tetrahedra. For faces, it contains one octagon, 14 squares and 16 triangles.
Cartesian coordinates
The coordinates of the square orthobicupolic ring are as follows:
(±(1+√2),±1,0,0);
(±1,±(1+√2),0,0);
(±1,±1,1,±1).
Equations
