对新的LA-群的探寻是一项有价值的活动。通过对p6阶群中的第四家族群的定义关系一般化后,再利用群的循环扩张理论和自由群理论对其进行推广,得到了有限p-群的一个重要的无限类,验证了其是LA-群,给出了它的一些性质,并进一步的求得在限定参数条件下所给群的性质和其自同构群的阶。
Exploring new LA-group is considered a valuable activity.After the forth family group of order p6is generalizated,an important infinite class of p-group is obtained by extending theory of cyclic group and free theory.It is proved that they are all LA-groups.Their some properties are given,and the order of its automorphism is then calculated in a limited parameter conditions.
