利用有限幂零群G的自同构群Aut(G)的阶来刻画群G的构造.在刻画的过程中,本文先通过某些有限P-群Q的自同构群Aut(Q)的阶来确定了群Q的结构,然后根据幂零群的性质:G可分解为它的所有Sylpi(G)(i=1,…,n)的直积,通过分类讨论的Aut(P1)阶,从而给出了自同构群阶为16p3(p为奇素数)的有限幂零群的完全分类,当群G没有Sylow 2-子群时;G有21种类型,当S2(S2∈Syl2(G))的阶分别为2,4,8,16时,群G分别有21,21,19,16这3种类型,最终确定在满足上述条件下的群G共有80种类型.
Finite Nilpotent Groups with Automorphism Groups of Order 16p3 (p prime )
This paper discusses the structures of nilpotent group G by using the oder of automorphism group G. In the process, first,We use the orders of automorphism group Q of some finite p-group Q to determine the structure of the Q group. We know nilpotent group G can decompose into the direct product of all its Sylow p-subgroups, then, by discussing the orders of automorphism group Pt,We can found out all the finite nilpotent groups when the order of automorphism group G equals 16p3 with p being odd primes.
