• Let q ³ 3 be an odd integer and let H(lq) be the Hecke group associated to q. Let m be a positive integer and Hm(lq) be the m-th power subgroup of H(lq). In this paper, authors consider the power subgroups of some Hecke groups. They determine the abstract group structure and generators of these subgroups and generalise the results regarding the relations between power subgroups and commutator subgroup, given for the modular group to Hecke groups.
