At various times, a journal for math software has been discussed. Here
is the math software journal for R. R probably has a much bigger

Hi,
I've written with my supervisor some code that computes the isogeny
class of a curve over QQ. I would like to check it with the entire
Cremona database overnight, but I'm not sure how to do that!
To do it case by case I would do something like:
sage: isogs, matrix = E.isogeny_class()
