Triangular-hexagonal prismantiprismoid

The bialternatosnub 3-6 duoprism or runcic snub rectified 3-4 duoprism is a convex isogonal polychoron that consists of 6 ditrigonal trapezoprisms, 6 triangular antiprisms, 6 triangular prisms and 18 wedges obtained through the process of bialternating (i.e. alternating two adjacent vertices) the 6-12 duoprism. However, it cannot be made uniform.
