Hexagonal-hexagonal prismantiprismoid

The bialternatosnub 6-6 duoprism or runcic snub rectified 6-6 duoprism is a convex isogonal polychoron that consists of 6 hexagonal antiprisms, 6 hexagonal prisms, 12 ditrigonal trapezoprisms and 36 wedges obtained through the process of bialternating (i.e. alternating two adjacent vertices) the 12-12 duoprism. However, it cannot be made uniform.
