Source: OEIS A060838, index n=6813, recording rank 3 for x^3+y^3=6813. The corresponding minimal model is y²+y=x³−429787. PARI/GP 2.17.4 returned exact rank bounds [3,3] and trivial torsion. All three supplied points pass exact membership. Minimal discriminant −79797593005443 = −3^5·757^4; conductor 139250907. This is a published OEIS source recovery.
