Pentagonal duoantiprism

The pentagonal duoantiprism, also known as the pentagonal-pentagonal duoantiprism, the 5 duoantiprism or the 5-5 duoantiprism, is a convex isogonal polychoron that consists of 20 pentagonal antiprisms and 50 tetragonal disphenoids obtained through the process of alternating the decagonal duoprism. However, it cannot be made uniform.
