Small complex icosidodecacron
(dual polyhedron)In geometry, the small complex icosidodecahedron is a degenerate uniform star polyhedron. It has 32 faces (20 triangles and 12 pentagons), 60 (doubled) edges and 12 vertices. All edges are doubled (making it degenerate), sharing 4 faces, but are considered as two overlapping edges as topological polyhedron.
It can be constructed from a number of different vertex figures.
As a compound
It can be seen as a compound of the icosahedron {3,5} and the great dodecahedron {5,5/2} where all vertices and edges coincide. The small complex icosidodecahedron appears to be an icosahedron because the great dodecahedron is completely contained inside the icosahedron.
