对两类几乎单群旗-传递作用于斯坦诺4-设计上情况进行了讨论. 得到了:设D=(X,B,I)是非平凡的斯坦诺4-设计,D的自同构群G旗-传递地作用在D上.若G是几乎单群,则Soc(G)不同构于单群HS(这里v=176)和CO3(这里v=276).
The case of two types of almost simple groups acting flag - transitivly on the Steiner 4 - Designs is discussed. The result shows: Let D = (X,B,I) be a non- trivial Steiner 4- design, and G be a flag- transitive automorphism group of D, if G is almost simple type , then Soc(G) is not isomorphic to HS ( v = 176 ) group and CO3 ( v = 276 ) group.
