有限p-群两个重要的类

Two Important Classes of p-groups

利用群的扩张理论得到有限p-群两个重要的无限类,给出它们的一些性质,并证明它们都是LA-群,从而得到若干新的LA-群.

We get two important infinite classes of p - groups by using the extension theory of group, give their some properties, in particular, show that they are all LA-groups and so a lot of new LA-groups are obtained.
