Classification of the non-trivial 2-(v, k, lambda) designs, with (r, lambda)=1 and lambda 1, admitting a non-solvable flag-transitive automorphism group of affine type

摘要

Non-trivial 2-(v, k, lambda) designs, with (r, lambda) = 1 and lambda > 1, admitting a non-solvable flag-transitive automorphism group of affine type are classified.
