摘要 设G是一个2-(v,k,1)设计的可解区组传递自同构群,且k≥3.若v>k(k-1)2-12,则v=pn,其中p为素数.进一步,当n为一个素数的幂,则G为旗传递或者G≤AΓL(1,pn). Let G be a soluble block-transitive automorphism group of 2-(v,k,1),design and k≥3.If v〉(k(k-1))/2-1)^2 then v=p, where p is a prime number and n is a positive integer. Furthermore, if n is a power ofa prime number, then G is flag-transitive or G≤AΓL(1,v).
