Triangular-square prismantiprismoid

The bialternatosnub 3-4 duoprism or runcic snub rectified 3-4 duoprism is a convex isogonal polychoron that consists of 4 ditrigonal trapezoprisms, 6 tetragonal disphenoids and 12 wedges obtained through the process of bialternating (i.e. alternating two adjacent vertices) the 6-8 duoprism. However, it cannot be made uniform.
