|New elldata package update (conductor up to 380000)|
Dear PARI users, John Cremona has extended his Elliptic Curve Data to all conductors < 380000 <http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/data/INDEX.html> I have updated the PARI package elldata to match. This package contains elliptic curves defined over the rationals representing all isogeny classes for all conductor at most 380000. Theses data are needed by ellsearch, ellidentify and ellgenerators and require PARI/GP 2.2.11 and up. The package can be downloaded from <http://pari.math.u-bordeaux.fr/packages.html> Thanks to John for providing this very useful database. At this point the package is a bit large, we might want to provide a smaller version for conductors <=100000 (or <=200000). If diskspace is an issue, you can compress all the elldata/ell* files using gzip, GP is able to read gziped files. Cheers, Bill.
