Rational 3-isogeny partner of curve #5415:
https://elliptic-rank.icarm.cloud/curve/5415
The source curve was submitted by Jesper Petersen and obtained through Mestre’s polynomial cube-completion construction from the integer sextuple (-115,-59,-53,67,73,87). The eleven source points were transported through the exact degree-3 isogeny and checked exactly on this minimal target model. Rank ≥11 is preserved under the rational isogeny. Rational torsion is trivial.
