Pentagonal-square prismantiprismoid

The pentagonal-square prismantiprismoid, also known as the edge-snub pentagonal-square duoprism or 5-4 prismantiprismoid, 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 edge-alternating the octagonal-decagonal duoprism. However, it cannot be made uniform.
