On the principal congruence subgroups of the Hecke-group H(√5)
Using the notion of quadratic reciprocity, we discuss the principal congruence subgroups of the Hecke group H(√5). -
One relator quotients of the extended modular group
In this paper, we obtain one relator quotients of the extended modular group by adding an extra relation to the existing two relations. Then, we show that some of one-relator quotients of are M*-groups.
