The rational 3-isogenous partner of our accepted rank-10 Mordell curve obtained from the Burkhardt quartic with parameters (u,v,w) = (7,-2,3), specialized at t = -208/211.
Constructed using the rational 3-isogeny y² = x³+B → y² = x³−27B. Rank is exactly 10 because the original curve has certified exact rank 10 and isogenous elliptic curves have equal Mordell–Weil rank.
