Hexagonal-square prismantiprismoid

The bialternatosnub 6-4 duoprism or runcic snub rectified 6-4 duoprism is a convex isogonal polychoron that consists of 4 hexagonal antiprisms, 4 hexagonal prisms, 12 rectangular trapezoprisms and 24 wedges obtained through the process of bialternating (i.e. alternating two adjacent vertices) the 8-12 duoprism. However, it cannot be made uniform.
