For an arbitrary partition \(\sigma\) of the set \(\mathbb{P}\) of all primes, a sufficient condition for the \(\sigma\)-subnormality of a subgroup of a finite group is given. It is proved that the Kegel–Wielandt \(\sigma\)-problem has a positive solution in the class of all finite groups all of whose nonabelian composition factors are alternating groups, sporadic groups, or Lie groups of rank 1.
