Triangular-square tetraswirlprism

The triangular-square tetraswirlprism is a convex isogonal polychoron and member of the duoprismatic swirlprism family that consists of 12 square antiprisms, 16 triangular antiprisms, and 144 phyllic disphenoids of three kinds. 2 square antiprisms, 2 triangular antiprisms, and 12 phyllic disphenoids join at each vertex.
