Elliptic Curve Rank Leaderboard

Obtained by a rational 3-isogeny from curve #4750, submitted by David Renshaw: https://elliptic-rank.icarm.cloud/curve/4750. The source commentary attributes the original Mordell curve y^2 = x^3 - 5721469548799 to Noam D. Elkies, “j=0, rank 15; also 3-rank 6 and 7 in real and imaginary quadratic fields”, NMBRTHRY post, 30 December 2009: https://listserv.nodak.edu/cgi-bin/wa.exe?A2=NMBRTHRY;6a3fad67.0912&S=. Applied the standard degree-3 isogeny from y^2 = x^3 + B to y^2 = x^3 - 27*B. Here B = -5721469548799, giving y^2 = x^3 + 154479677817573. The coordinate map is X = (x^3+4*B)/x^2, Y = y*(x^3-8*B)/x^3. Ten 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 3535403090166097125372979308. Source-attributed existing curve.
