Pentagonal-square prismantiprismoid

The bialternatosnub pentagonal-square duoprism or bialternatosnub 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 octagonal-decagonal duoprism. However, it cannot be made uniform.
