Square-square prismantiprismoid

The square-square prismantiprismoid, also known as the edge-snub square-square duoprism or 4-4 prismantiprism, is a convex isogonal polychoron that consists of 4 square antiprisms, 4 square prisms, 8 rectangular trapezoprisms and 16 wedges obtained through the process of edge-alternating the octagonal duoprism. However, it cannot be made uniform.
