Let be a fixed odd prime number. In this note we study the class of finite -groups admitting an automorphism of order such that and for all . In this paper we prove that if the derived length of is and is nilpotent of class , then the nilpotency class of is bounded by a function depending only on , and . We prove also that if and is nilpotent of class , then is nilpotent of class at most .
