Rational 3-isogeny partner of ICARM curve #5459:
https://elliptic-rank.icarm.cloud/curve/5459
The source curve was submitted by Daniel Błażewicz. Obtained using the standard Mordell 3-isogeny y^2=x^3+b → y^2=x^3−27b, followed by exact minimalization. The eight source points were mapped through the isogeny and checked exactly.
PARI/GP 2.17.4 returned rank bounds [8,8], trivial rational torsion, conductor 22183815730567497075 and minimal discriminant -404300041689592634191875. Exact quadratic-character certification at 15 good primes gives an F_2 matrix of rank 8, proving the eight submitted points independent.
