The Mordell-Weil group E(K)E(K) of an elliptic curve EE over a number field KK is a finitely generated abelian group, explicitly described by giving a Z\Z-basis for the group, equivalently, a (minimal) set of Mordell-Weil generators, each of which is a rational point on the curve.

The generators consist of rr non-torsion generators, where rr is the rank of E(K)E(K), and up to two torsion generators, which generate the torsion subgroup E(K)torE(K)_{\textrm{tor}}.
