Are these the pickles William has sitting in his home directory (the ones we computed last summer on ranger/lonestar)? If so, they don't unpickle in anything between ~3.0.5 and the first 3.3.alpha after the San Diego conference. So they just don't work in 3.2.3.
The details, if you're interested: we reorganized the classes for the congruence subgroup objects in Sage at the end of the summer, and made it so that, e.g., Gamma0(7) is a unique object. This was definitely a good idea for doing a bunch of stuff with them. Unfortunately, this broke the old pickles, until the patch in one of the 3.3.alphas. It's still not 100% perfect -- based on some pointers from Carl Witty, there's probably a yet better way to set things up, which I'm going to probably do and then "update" (re-brine?) all the old pickles on sage.math ... at some point soon (read: after my thesis is turned in). -cc On Thu, Feb 12, 2009 at 2:25 PM, salmanhb <salma...@gmail.com> wrote: > > Hi, > > I used the following code: > > /home/sbutt/frg/lcalc/ap-to-an.sage > > adapted from Craig's code on sage.math and it ran perfectly well on v. > 3.3.alpha3 (though it did complain about the data being stored in an > old format).
