摘要

Let A and G be finite groups such that A acts coprimely on G via automorphisms. A subgroup H of G is said to satisfy the IC-property if the intersection of H and [HG] meets certain specified conditions. In this paper, we investigate the structure of the finite group G under the assumption that certain maximal A-invariant subgroups of G possess the IC-property and obtain some new results in the coprime action setting.
