Abstract
Recently, I. J. Leary and A. Minasyan studied the class of groups defined as commensurating HNN-extensions of . This class, containing the class of Baumslag-Solitar groups, also includes other groups with curious properties, such as being CAT(0) but not biautomatic. In this paper, we classify the groups up to isomorphism.
