Snub operation with the faces of the Dodecahedron: From Dodecahedron to Icosahedron. Rhombicosidodecahedron. Snub Dodecahedron.
A snub-operation can be seen by moving the slider t (0≤t≤1) for expanding faces of a polyhedron : t=0 satisfy Dodecahedron, t= 0.632785313013558 Rhombicosidodecahedron and t=0 -Icosahedron. You can use the slider α to set the rotation of faces relative to their centers and under certain conditions to get: Snub Dodecahedron.
