Rational 3-isogeny partner of https://elliptic-rank.icarm.cloud/curve/5384, submitted by Daniel Błażewicz. Completing the square gives the Mordell model Y^2 = x^3 + 97491937/4; its standard rational 3-isogeny gives Y^2 = x^3 - 27*97491937/4, whose minimal integral model is [0,0,1,0,-658070575]. 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 85542100020107721 as the source curve. No original-discovery claim.
