Triangular-dodecagonal duoprismatic prism

The triangular-dodecagonal duoprismatic prism or tratwip, also known as the triangular-dodecagonal prismatic duoprism, is a convex uniform duoprism that consists of 2 triangular-dodecagonal duoprisms, 3 square-dodecagonal duoprisms and 12 triangular-square duoprisms.
