This paper presents a new approach to 2 3 k -generated groups. We first show that the triangle group T 2 3 k is isomorphic to a subgroup of a two-dimensional projective unitary group over a ring. Then our main purpose is to determine the values of k for which this subgroup coincides with the whole p
