An archimedean group is a strictly ordered group which satisfies the Archimedean property, in which every positive element is bounded above by a natural number.
So an archimedean group has no infinite elements (and thus no non-zero infinitesimal elements).
Every archimedean group is an abelian group and has no bounded cyclic subgroups. Every archimedean group admits an embedding into the group of real numbers.
Every archimedean group is a flat module and a torsion-free group.
Every Dedekind complete archimedean group is isomorphic to the integers, if the group is not dense, or the Dedekind real numbers, if the group is dense.
