Description (last modified by )
Hi William, I just downloaded the sage version of the SteinWatkins database of (a subset of) the elliptic curves of conductor < 10^8, because I need a supply of small curves with large rational torsion subgroups. I looked in sage/local/share/stein_watkins/format.txt and it says that the torsion subgroup is given as follows: torsion_subgroup  n or nx, where n means Z/nZ and nx means Z/2Z x Z/2nZ. But in the actual tables, nx seems to indicate Z/2Z x Z/nZ (instead of 2nZ), because the values that appear are 2x, 4x, 6x, and 8x. I hope all is well with you! Thanks   Everett
We simply need the updated format.txt
from http://modular.math.washington.edu/ecdb/

Note: See
TracTickets for help on using
tickets.
This is fixed upstream (http://modular.math.washington.edu/ecdb/format.txt), so we should add the right
format.txt
in the package.
