Letσ= {σi|i∈I} be some partition of the set of all primes ℙ,Ga finite group andσ(G) = {σi|σi∩π(G) ≠ ∅}. A setHof subgroups ofGis said to be acomplete Hall σ-setofGif every member ≠ 1 ofHis a Hallσi-subgroup ofGfor someσi∈σandHcontains exactly one Hallσi-subgroup ofGfor everyσi∈σ(G). A subgroupHofGis said to be:σ-semipermutable in G with respect to HifHHix=HixHfor allx∈Gand allHi∈Hsuch that (|H|, |Hi|) = 1;σ-semipermutable in GifHisσ-semipermutable inGwith respect to some complete Hallσ-set ofG. We study the structure ofGbeing based on the assumption that some subgroups ofGareσ-semipermutable inG.
