Bulletin of the Malaysian Mathematical Sciences Society, 33(2), 205-210.0126-6705http://hdl.handle.net/11452/28396Let lambda = root D where D is a square free integer such that D = m(2)+1 for m = 1,3, 4, 5,..., or D = n(2) - 1 form = 2, 3, 4, 5,.... Also, let H(lambda) be the Hecke group associated to A. In this paper, we show that the units in H(lambda) are infinite pure periodic lambda-continued fraction for a certain set of integer D, and hence can not be cusp points.eninfo:eu-repo/semantics/closedAccessHecke groupFuchsian groupContinued fractionCusp pointPrincipal congruence subgroupsMathematicsArticle0002776789000042-s2.0-77953037019205210332MathematicsHecke Groups; Modular Forms; Graph
