e.g, set of (Q,+) it is an abelian group but not cyclic. A cyclic group is generated by a single element and every element in a cyclic group is some power of a generator. This website is no longer maintained by Yu. Let G be a cyclic group and g be a generator of G. Let a, b ∈ G. Then there exist x, y ∈ ℤ such that a = g x and b = g y.

Every abelian subgroup of a Gromov hyperbolic group is virtually cyclic. Why don't libraries smell like bookstores?
