Rational 3-isogeny partner of curve #5215: https://elliptic-rank.icarm.cloud/curve/5215. The source Mordell curve is y^2 + y = x^3 - 1892169, submitted by Daniel Błażewicz with six independent points. Applying the standard Mordell 3-isogeny and returning to a minimal integral model gives y^2 + y = x^3 + 51088556. The six submitted points are exact images of the source generators under that isogeny.
