Enumerative Theory of Maps (Mathematics and Its Applications 468) (2000. 415 S. 240 mm)

As soon as the problem without considering the symmetry is solved for one kind of map, the general problem with symmetry can always, in principle, be solved from what we have known about the automorphism of a polyhedron, a synonym for a map, which can be determined efficiently according to another monograph of the present author [Liu58].
