Commentary

Rank 13 curve due to Eroshkin (2007), listed on Dujella's high-rank elliptic curves with prescribed torsion page for torsion group Z/3Z: https://web.math.pmf.unizg.hr/~duje/tors/z3old8910111213.html. The model is y^2 + x*y = x^3 - 560715933702165990261993692150795879540*x + 5299428030171662962897867758309003693598430128674403539600, with the 13 listed integral independent points.
