本文研究了非平凡Steiner 4设计的自同构群是旗传递的情形.利用有限2传递置换群的分类,得到了旗传递非平凡Steiner 4设计的自同构群的基柱不是Suzuki群.
This article studies the case that the flag-transitive non-trivial Steiner 4-designs' automorphism groups is an almost simple type group.By using the classification of the finite doubly transitive permutation groups,we obtain the socle of the automorphism groups is not Suzuki group.
