Rational 3-isogeny partner of https://elliptic-rank.icarm.cloud/curve/5378, submitted by Daniel Błażewicz. Starting from the Mordell curve y^2 = x^3 + 974152504, apply the standard rational 3-isogeny to y^2 = x^3 - 27*974152504 = x^3 - 26302117608. The seven displayed points were recovered and checked on this endpoint; PARI/GP returned rank bounds [7,7] and a nonzero Neron-Tate height determinant. Same conductor 50537029049971776 as the source curve. No original-discovery claim.
