• openAccess   Indices of Maximal Invariant Subgroups and Solvability of Finite Groups 

      shao, Changguo; Beltrán, Antonio Springer Verlag (2019)
      Let A and G be finite groups and suppose that A acts coprimely on G via automorphisms. We study the solvability and supersolvability of G when certain proper maximal A-invariant subgroups of G have prime index or when ...
