Commentary

Provenance: Elkies-Watkins, "Elliptic curves of large rank and small conductor" (arXiv:math/0403374), Table 4 low absolute-discriminant list for r=10: [1,-1,0,-1536664,648294124], |Delta|=50881111474471687972; their I-column records 207 integral x-coordinates. Also appears in Table 2 with conductor N=25440555737235843986 and |Delta|/N=2. The submitted points certify rank >= 10 here.
