dc.description.abstract	Let A and B be maximal subgroups of PSL2(ℝ) that commensurable with PSL2(ℤ) (S and T are commensurable with each other if S ∩ T is of finite index in both S and T). In this article, we determine the index [A: A ∩ B] and the level of A ∩ B (Appendix A). © 2004 Elsevier Inc. All rights reserved.
