The trigonal magnabicupolic ring is a CRF polychoron among the segmentochora enumerated by Klitzing (K4.7.2). It is a member of the family of bicupolic rings, which contains eight other similar polychora.
Dichoral angles
- Between hexagonal prism and square pyramid: atan(√5) ≈ 65.9051574479°
- Between hexagonal prism and triangular cupola: atan(√(5/3)) ≈ 52.2387560930°
- Between hexagonal prism and triangular prism: acos(2/3) ≈ 48.1896851042°
- Between two triangular cupolae: 75.5224878141°
