The square magnabicupolic ring is a member of the family of bicupolic rings, which contains eight other similar polychora. It can be constructed by the (partial) Stott expansion of the cubic pyramid.
Dichoral angles
- Between square cupola and octagonal prism: 45° (exact)
- Between square pyramid and octagonal prism: 45° (exact)
- Between triangular prism and octagonal prism: acos(sqrt(2/3)) ≈ 35.264389682754654°
