Let q be an odd integer >3 and let G q be the Hecke group associated to q. Let ({) be a prime ideal of Z[\* q ] and G(q, {) the principal congruence subgroup of G q associated to {. We give a formula for [G q : G(q, {)], the index of the principal congruence subgroup G(q, {) in G q . We also give fo
