Let G be a block-primitive automorphism group of a 2-(v, k, 1 design. If G is isomorphic to PSL (3,q) where q is odd,the......

It is proved that if D be a 2-(v,k,1) design with G≤ Aut D block primitive then G does not have a Suzuki group Sz(q) a ......

A 2 - (v, k, 1) design D = (P,B) is a system consisting of a finite set P of v points and a collection B of k-subsets of......

It is proved that if D be a 2-(v,k,1) design with G≤Aut D block primitive then G does not have a Suzuki group Sz(q) as ......

Let G be a block-primitive automorphism group of a 2-(v,k, 1) design. If G is isomorphic to PSL (3,q) where q is odd,the......

本文证明了当2-(v,k,l)设计的自同构群G的基柱soc(G)=^2F4(q^2)时，Buekenhaut-Delandtsheer-Doyen猜想成立，即自同构群G的基柱为Ree......
