Finite Groups with Automorphism Groups Having Orders 4pq2 (2 ＜ p ＜ q) Ⅱ

摘要

The authors study and classify finite groups with their automorphism groups having orders 4pq2,where p and q are 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.
