Elldata package update (fixed generators for conductor 130000-139999) |
Hello PARI users, Alan Simpson discovered a problem with the curve generators in the elldata package for conductor 130000 to 139999: some of them were not on the curves. However the generators on John website (the allgens files) were correct. John has provided me with a fixed PARI data, so I have updated the PARI package elldata - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - elldata is the PARI/GP version of J. E. Cremona Elliptic Curve Data <http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/data/INDEX.html> This package contains elliptic curves defined over the rationals representing all isogeny classes for all conductor at most 220000. Theses data are needed by ellsearch and ellidentify and require PARI/GP 2.2.11 and up. The package can be downloaded from <http://pari.math.u-bordeaux.fr/packages.html> Cheers, Bill.
