Triangular-snub dodecahedral duoantiprism

The triangular-snub dodecahedral duoantiprism, or trasniddap, is a convex isogonal polyteron that consists of 6 snub dodecahedral antiprisms, 12 triangular-pentagonal duoantiprisms, 20 triangular-triangular duoantiprisms, 30 digonal-triangular duoantiprisms, and 360 sphenoidal pyramids. 2 snub dodecahedarl antiprisms, 1 triangular-pentagonal duoantiprism, 1 triangular-triangular duoantiprism, 1 digonal-triangular duoantiprism, and 5 sphenoidal pyramids join at each vertex. It can be obtained through the process of alternating the hexagonal-great rhombicosidodecahedral duoprism. However, it cannot be made uniform.
