Let G be a finite group and Le(G)={xGxe=1}, where e is a positive integer dividing |G|. How do bounds on |Le(G)| influence the structure of G? Meng and Shi [Arch. Math. (Basel) 96 (2011), 109–114] have answered this question for |Le(G)|2e. We generalize their contributions, considering the inequality |Le(G)|e2 and finding a new class of groups of whose we study the structural properties.

Keywords: Metacyclic groups; Frobenius' theorem; p-groups; Sylow subgroups
