This article is a contribution to the study of the automorphism groups of 2-(v,k,1) block designs. In particular we look at the unsolvable block transitive automorphism groups of 2-(v,5,1) designs and prove the following theorem. Main TheoremIf a blo

Let D be a 2-(v,k,1) design, G be a group of automorphisms of D, and suppose the socle of G is an alternating group An with n⩾5. If G is block-primitive then G is also point-primitive.

Let G be an automorphism group of a 2−(v, k, 1) design. In this paper, we prove that if G is line-primitive and k/(k, v)⩽10, then G is also point-primitive.

Suppose that an almost simple group G acts line transitively on a finite linear space S. Let G"x be a point stabilizer in G and suppose that G has socle T, a simple group of Lie type. In this paper we show that if [email protected]?G"x is a parabolic
