A great dodecahedron
A great dodecahedron: the faces are pentagons, that form a 5-pointed star around each vertex. It can be reproduced between the mirrors in the kaleidoscope relative to the group of symmetry of the dodecahedron.
This image has been used in the posters on polyhedra realized for the exhibition Simmetria, giochi di specchi - Symmetry, playing with mirrors.
