A rhombic dodecahedron
A rhombic dodecahedron has 12 faces that are rhombuses and are all the same. They join together in some vertices at 3 o 3 and in others at 4 to 4. It is the dual of the cuboctahedron (3,4,3,4).
This picture has been used for the posters on polyhedra for the exhibition Simmetria, giochi di specchi - Symmetry, playing with mirrors.
