It is often very difficult to identify the structure of the automorphism group and the inner automorphism group of a group, and there is no general theory and method.
确定一个群的自同构群和内自同构群的结构往往十分困难，还没有一般性的理论及方法。
Under this assumption, the present paper further gives a characterization for the automorphism group of C( G, S) in terms of the quotient di-graph and the kernel K.
在这个假定下，我们进一步根据商有向图及核K为C（G，S）的自同构群刻划出了一系列特性。
