摘要
In this paper, all non-symmetric 2 (nu, k, lambda) designs with lambda >= (r, lambda)(2) are classified which admit a flag-transitive group of automorphisms with an alternating socle. Up to isomorphism, our classification shows exactly 20 such designs, and, for each of these designs, we explicitly determine the corresponding flag-transitive automorphism groups.
