Abstract

If G is a finite group and if A is a group of automorphisms of G whose fixed point subgroup is C G (A) then every subgroup F of C G (A) acts on the set of orbits of A in G. The peculiarities of this action are used here to derive several results on the number of orbits of A in an economical manner.
