Comment:
Salut Jean-Phillippe,
Thanks for your corrections! The branch is a fast forward. So you have to
delete your previous branch. Your commit is preserved (it is now 08df5b4).
I added three commits for better compatibility with the previous version:
- adding a `minpoly` and `field_order` methods as it was requested in
[comment:23 comment:23] (see also #18266 for a potential improvement)
- adding a `__neg__` (it is now faster to do `-E(3)`)
Vincent
