Rational 3-isogeny partner of curve #3080:

The source curve is attributed to Elkies–Rogers (2004) in Dujella’s Z/3Z table, curve entry 51:

The nine source points were transported through the exact degree-3 isogeny and checked exactly on this minimal target model. Rank ≥9 is preserved under the rational isogeny. Rational torsion is trivial. This target is a cube-sum curve.
