Pentagonal-snub dodecahedral duoantiprism

The pentagonal-snub dodecahedral duoantiprism, or pesniddap, is a convex isogonal polyteron that consists of 10 snub dodecahedral antiprisms, 12 pentagonal-pentagonal duoantiprisms, 20 triangular-pentagonal duoantiprisms, 30 digonal-pentagonal duoantiprisms, and 600 sphenoidal pyramids. 2 snub dodecahedral antiprisms, 1 pentagonal-pentagonal duoantiprism, 1 triangular-pentagonal duoantiprism, 1 digonal-pentagonal duoantiprism, and 5 sphenoidal pyramids join at each vertex. It can be obtained through the process of alternating the decagonal-great rhombicosidodecahedral duoprism. However, it cannot be made uniform.
