Square-pentagonal duoantiprism

The square-pentagonal duoantiprism, also known as the 4-5 duoantiprism, is a convex isogonal polychoron that consists of 8 pentagonal antiprisms, 10 square antiprisms and 40 digonal disphenoids obtained through the process of alternating the octagonal-decagonal duoprism. However, it cannot be made uniform.
