Pentagonal-square prismantiprismoid

The bialternatosnub 5-4 duoprism or runcic snub rectified 5-4 duoprism is a convex isogonal polychoron that consists of 4 pentagonal antiprisms, 4 pentagonal prisms, 10 rectangular trapezoprisms and 20 wedges obtained through the process of bialternating (i.e. alternating two adjacent vertices) the 8-10 duoprism. However, it cannot be made uniform.
