Abstract
An elliptic curve over is said to be good if where is the conductor of and and are the invariants associated to a global minimal model of . In this article, we generalize Masser's Theorem on the existence of infinitely many good elliptic curves with full -torsion. Specifically, we prove via constructive methods that for each of the fifteen torsion subgroups allowed by Mazur's Torsion Theorem, there are infinitely many good elliptic curves with .
