ABSTRACT

is the
disjoint union of for
all , where is the
set of all roots of primitive second degree equations , with reduced discriminant equal
to *k*^{2}m. We study the action of two Hecke groups—the full modular group and
the group of linear-fractional transformations on . In particular, we investigate the action of on for
finding different orbits.
