群G的子群H称为在G中5条件置换嵌入(简称S-C置换嵌入),如果对于任意的p∈π(H),H的每个Sy—lowP子群都是G的某个S条件置换子群的SylowP子群.本文利用S-C置换嵌入子群,得到了有限群的一个新的特征性定理,并由此推广了一系列已知的结论.
A subgroup H of a group G is said to be S-conditionally permutably embedded(or in brevity, S-C-permutably embedded) in G, if for each p∈π(H) every Sylow p-subgroup of H is a Sylow p-subgroup of some S-conditionally permutable subgroup of G. By using the concept of S-C-permutably embedded subgroup, some new characterizations of finite groups are obtained, and several known results are generalized.
