而对于亚循环群的DCI -性,目前所知的结果并不多。
But for the problem of the DCI-property of metacyclic groups, there are still not many results.
具体地构造出两个有限循环群的自由积的外自同构群,并给出了其阶的计算公式。
The outer automorphism group of the free product of two cyclic groups is constructed, and two exact formulas for calculating its order are established.
