The uniform polyhedra include the Platonic solids (consisting of equal convex regular polygon faces), Archimedean soldis (consisting of convex regular faces of more than one type). Convex polyhedrons are also known as Euler polyhedrons, and can be defined by the equation E = v + f - e = 2, where v is the number of vertices, f is the number of faces, and e is the number of edges.
