Square-square prismantiprismoid

The bialternatosnub square-square duoprism or bialternatosnub 4-4 duoprism 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 bialternating (i.e. alternating two adjacent vertices) the octagonal duoprism. However, it cannot be made uniform.
