作者与他们有 p 和 q 是素数的订单 4pq ², 的自守组一起学习并且分类有限的组以便 2 p q。在 2013，第一和第三个作者分类这种类型的 nilpotent 组；这里，作者与他们有订单 4pq ² 的自守组一起给那些有限 non-nilpotent 组的分类。

英文摘要：

The authors study and classify finite groups with their automorphism groups having orders 4pq2, where p and q axe primes such that 2 〈 p 〈 q. In 2013 the first and the third authors classified the nilpotent groups of this kind; here the authors give the classification of those finite non-nilpotent groups with their automorphism groups having orders 4pq2.
