A t-(v,k,λ)design is said to be G-point-primitive or G-block-transitive,if its automorphism group G acts primitively on the point set or transitively on the block set,respectively.In this paper we begin by extending ...
This article is a contribution to the study of the automorphism groups of designs. Let be a non-trivial design where for some positive integer , and is block-transitive. If the socle of G is isomorphic to the simpl...

This paper is a contribution to the study of the automorphism groups of 2 - (v, k, 1) designs. Let D be a 2 - (v, 23, 1) design and G a block-transitive and point-primitive group of automorphism of D. Then the soc...

In recent years, there has been a great deal of research concerning the flag- transitive t-designs, however, few about the block-transitive t-designs with t large (t 〉 4). In 1993, Cameron and Praeger conjectured t...

This article is a contribution to the study of block-transitive automorphism groups of 2-(v,k,1) block designs. Let D be a 2-(v,k,1) design admitting a block-transitive, pointprimitive but not flag-transitive auto...
