Digonal-snub dodecahedral duoantiprism

The digonal-snub dodecahedral duoantiprism, or disniddap, is a convex isogonal polyteron that consists of 4 snub dodecahedral antiprisms, 12 digonal-pentagonal duoantiprisms, 20 digonal-triangular duoantiprisms, 30 tetragonal disphenoidal antiprisms, and 240 sphenoidal pyramids. 2 snub dodecahedral antiprisms, 1 digonal-pentagonal duoantiprism, 1 digonal-triangular duoantiprism, 1 tetragonal disphenoidal antiprism, and 5 shenoidal pyramids join at each vertex. It can be obtained through the process of alternating the square-great rhombicosidodecahedral duoprism. However, it cannot be made uniform.
