In geometry, the small ditrigonal icosidodecahedron is a nonconvex uniform polyhedron, indexed as U30. It has extended Schläfli symbol a, as an ''altered dodecahedron'', and Coxeter diagram . It is constructed from Schwarz triangle (3 3 5/2) with Wythoff symbol 3 | 5/2 3, and Coxeter diagram File:Small ditrigonal icosidodecahedron cd.png. Its hexagonal vertex figure alternates equilateral triangle and pentagram faces. ==Related polyhedra== Its convex hull is a regular dodecahedron. It additionally shares its edge arrangement with the great ditrigonal icosidodecahedron (having the triangular faces in common), the ditrigonal dodecadodecahedron (having the pentagrammic faces in common), and the regular compound of five cubes.
