  "commentary": "Obtained by a rational 3-isogeny from curve #4827, submitted by Daniel Błażewicz: https://elliptic-rank.icarm.cloud/curve/4827.\r\n\r\nThe source model is y^2 + y = x^3 - 6. Its public entry supplies two rational points and no commentary identifying an earlier source.\r\n\r\nCompleted the square with Y = y + 1/2, giving Y^2 = x^3 + B with B = -23/4. Applied the standard degree-3 isogeny X = (x^3+4*B)/x^2, V = Y*(x^3-8*B)/x^3, then set y' = V - 1/2. The resulting integral model is y'^2 + y' = X^3 + 155.\r\n\r\nTwo supplied rational points transported through this map and checked exactly on the target curve. Rational torsion trivial. Same rank and conductor as the source; conductor 4761. Source-attributed existing curve.",
