Convex 3-polytopes with exactly two types of edges
An edge of a convex 3-polytope is of type (a,b;m,n) if its vertices are of valence a and b, and if the two faces which contain it are m- and n- gons. The authors describe here all such polytopes which have just two types of edges. They fall into a number of families. Most of these families are finite, but several are infinite (for example, pyramids, bipyramids and their dual prisms).
