Let V be a faithful G-module for a finite group G and letp be a prime dividing |G|. An orbit v(G) for the action of G onV is regular if |v(G)|=|G:C-G(v)|=|G|, and is p-regular if |v(G)|(p)=|G:C-G(v)|(p)=|G|(p). In this note, we study two questions, one by the authors and one by Isaacs, related to the p-regular orbits and regular orbits of the linear group actions.
