Polyhedra

Some virtual leaflets ("The five regular polyhedra" and "Why only five") go over the regular polyhedra; others explore a family of polyhedra which are not regular but they look "rather" symmetric (the so-called "uniform polyhedra").

Moreover, some go over an incursion to the land of "The regular star polyhedra". Finally, here you find a virtual leaflet on "Euler's formula" which connects the number V of vertices, the number E of edges and that of faces F.
