In this paper it is proved that a finite group G with an automorphism α of prime order r, such that C G ⁢ α = 1 is contained in a nilpotent subgroup H, with H , r = 1 , is nilpotent provided that either H is odd or, if H is even, then r is not a Fermât prime.

A finite solvable group G is called an X-group if the subnormal subgroups of G permute with all the system normalizers of G. It is our purpose here to determine some of the properties of X-groups. Subgroups and quotient groups of X-groups are X-groups. Let M and N be normal subgroups of a group G of relatively prime order. If G/M and G/N are X-groups, then G is also an X-group. Let the nilpotent residual L of G be abelian. Then G is an X-group if and only if G acts by conjugation on...
