### Abstract

We determine the set of generators of arithmetic Fuchsian groups
$\Gamma $ with signature
(0; **e**_{1}, **e**_{2}, **e**_{3},
**e**_{4}) which are the subgroups
of the normalizers $\Gamma *($**A**, **O**)
of maximal orders **O**
in division quaternion algebras **A** over the rational number field **Q**
