Abstract: A generalized Baumslag–Solitar group (GBS-group) is a finitely generated group acting on a tree with infinite cyclic edge and vertex stabilizers. It is known that the outer automorphism groups of some GBS groups contain some p-torsion of unbounded order. We prove that in this case the prime p divides the integral modulus of G. This result answers Levitt’s question.
