Suppose that G is a finite group and H is a subgroup of G. H is called ss-quasinormal in G if there is a subgroup B of G such that G=HB and H permutes with every Sylow subgroup of B; H is called weakly s-supplemented in G if there is a subgroup T of G such that G=HT and H⋂T≤HₛG, where HₛG is the sub...
