摘要
具有良好传递性的区组设计是代数组合学研究的一个重要领域.重点研究旗传递6-设计,并证明如果一个6-(v,k,λ)设计允许一个旗传递自同构群,则λ>20.
The block combinatorics. It mainly designs with good transitivity was an important research field of algebraic studied the flag-transitive 6-designs and it was proved that if a design allowed a flag -transitive automorphism group, then λ〉20.
