Square-hexagonal tetraswirlprism

The square-hexagonal tetraswirlprism is a convex isogonal polychoron and member of the duoprismatic swirlprism family that consists of 16 hexagonal gyroprisms, 24 square gyroprisms, and 288 phyllic disphenoids of three kinds. 2 hexagonal gyroprisms, 2 square gyroprisms, and 12 phyllic disphenoids join at each vertex. It can be obtained as a subsymmetrical faceting of the hexadecagonal-icositetragonal duoprism.
