Pentagonal-square prismantiprismoid

The pentagonal-square prismantiprismoid or pispap, 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. 1 pentagonal antiprism, 1 pentagonal prism, 2 rectangular trapezoprisms, and 3 wedges join at each vertex. It can be obtained through the process of alternating one class of edges of the octagonal-decagonal duoprism so that the octagons become rectangles. However, it cannot be made uniform, as it generally has 4 edge lengths..
