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

Normalizers of 1 0 (m)+w 2 and 1 0 (m)+w 3 in PSL 2 (R) are determined. The determination of such normalizers enables us to determine the normalizers (in PSL 2 (R)) of the congruence subgroups G 0 4 (A) and G 0 6 (A) of the Hecke groups G 4 and G 6 .
