Abstract
In this article, we study a class of groups which are commensurable with a direct product of the discrete Heisenberg group and a free abelian group, or a free abelian group by using zeta functions of groups defined by Grunewald, Segal, and Smith as generating functions of the number of subgroups of given index $n$. We will show that zeta functions determine their isomorphism classes for groups belonging to the above class.
