Diminished rhombicosidodecahedron

The diminished rhombicosidodecahedron is one of the 92 Johnson solids (J76). It consists of 5+5+5 triangles, 5+5+5+10 squares, 1+5+5 pentagons, and 1 decagon. It can be constructed by removing one of the pentagonal cupolaic caps of the small rhombicosidodecahedron.
