Let G be a group and Aut(G) be its automorphism group. An automorphism α of G is called a commuting automorphism if α(x)x = xα(x) for all x ∈ G. The set of all commuting automorphisms of G is denoted by A(G). We find some cases when A(G) is a subgroup of Aut(G).

关于一些有限p群的通态自同构

令G为一组，Aut（G）为其自同构组。一个自同构α的ģ被称为通勤构如果α（X）X =Xα（X）对于所有的x∈ģ。G的所有通勤自同构的集合由A（G）表示。我们发现当A（G）是Aut（G）的子组时的一些情况。
