John Cremona tells me that: "All data for elliptic curves of conductors
from 130k to 170k is at
http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/data/ and also as a tar
file at
http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/ecdata-2011-07-26.tgz
-- not to mention at http://code.google.com/p/ecdata/ !"
The goal of this ticket is to:
(1) Create a new drop-in-replacement sqlite database that has the data up
to level 10000, which will be included standard with Sage.
(2) Create a new sqlite database that has the data up to level 170000,
which will be an optional spkg.
This is complicated because the current packages in Sage use ZODB. Also,
Cremona's database format has changed somewhat.
There is now a patch that depends upon #11642
