This is for a 2.8.10 installation so apologies if it has been fixed. The file examples/latex_embed/E2.sobj contains bad cached data so that when you run sage example.sage you get a run-time error, even though example.tex is correct! The clue came from looking at the backup file #example.tex#.

Thanks, and next time I'll make the trac myself (and after SD6 I may even fix some things myself, you never know). Anyway I had never seen the latex_embed stuff before -- it's nice! John On 06/11/2007, William Stein [EMAIL PROTECTED] wrote: On 11/6/07, John Cremona [EMAIL PROTECTED] wrote:

I stumbled over #262 http://trac.sagemath.org/sage_trac/ticket/262 again. Here Graeme Taylor proposes his implementation of point counting of elliptic curves over GF(p^n) with coefficients in GF(p) in Weierstrass form. He describes the background at:

You are right of course -- one should always compute the order over the smallest field of definition and then use the easy formula to get the order of E(GF(q^d)) from that of E(GF(q)). While you are at it you should not stop at the smallest field containing the coefficients of the given curve,
