Rational 2-isogeny partner of curve #5349: https://elliptic-rank.icarm.cloud/curve/5349. Obtained from the Aguirre–Castaneda–Peral parametrization at tuple (3,8,16,30), reduced by rational fourth-power scaling. Reference: "High rank elliptic curves with torsion group Z/(2Z)", Math. Comp. 73 (2004), 323–331, doi:10.1090/S0025-5718-03-01547-3. Eight rational points transported through the isogeny and checked exactly. Rank ≥8 follows from the source curve through the rational isogeny. Rational torsion C2.
