New elldata package update (conductor up to 320000)

[Bill Allombert <Bill.Allombert@math.u-bordeaux1.fr>]

Dear PARI users,

It is my pleasure to announce that John Cremona has extended his Elliptic Curve Data 
to all conductors < 320000 and it now includes more than two millions curves.
<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 320000. 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.

Cheers,
Bill.
