Dear Fausto,

If one refers to a 3-dimensional convex polyhedron as being
combinatorially regular, if all its vertices have the same number of
edges at each vertex and all the faces have the same number of sides,
then it is easy to prove from Euler's polyhedral formula that there are
only 5 combinatorially regular examples, and these correspond to the
classical Platonic solids.

Best wishes,

Joe
