A group is termed a locally cyclic torsion-free group if it satisfies the following equivalent conditions:

  1. It is both a locally cyclic group (i.e., every finitely generated subgroup is cyclic) and a torsion-free group (i.e., no non-identity element has finite order).
  2. It is isomorphic to a subgroup of the group of rational numbers.
