a simple classification of finite groups of order p^2q^2

‎suppose g is a group of order p^2q^2 where p>q are prime numbers and suppose p and q are sylow psubgroups and sylow qsubgroups of g, ‎respectively‎. ‎in this paper‎, ‎we show that up to isomorphism‎, ‎there are four groups of order p^2q^2 when q and p are cyclic‎, ‎three groups when q is a cyclic and p is an elementary ablian group‎, ‎p^2+3p/2+7 groups when q is an elementary ablian group and p is a cyclic group and finally‎, ‎p‎ + ‎5 groups when both q and p are elementary abelian groups.‎
