Looks like a linbox problem:
sage: J = jordan_block(0, 31).change_ring(QQ)
sage: (J^2).charpoly(algorithm='generic')
x^31
sage: (J^2).charpoly(algorithm='linbox') # the default
x^16

Sure it may be nice, but does not seem a priority to me...

Hello group,
I realised that extended GCD for several integers is not implemented in
Sage (i.e. xgcd2([a1, ..., an]))
Actually this feature already exists in Magma :
> ExtendedGreatestCommonDivisor([385, 231, 165, 105]);
1 [ -2, 1, 2, 2 ]
It could be interesting to have something like :
g, u
Sounds like a good suggestion. Do you want to create a trac account so
that you can create the ticket?

The other day I was visiting a local biotech company, and when I mentioned
to one of their bioinformatics people I worked with Sage, he immediately
was very enthusiastic. Turns out that he used to work at NIH, and they use
Sage, because...

Note that this is implemented in various places, e.g.
https://github.com/sagemath/sagelib/blob/master/sage/ext/multi_modular.pyx
, but certainly a general user-friendly function would be nice to
have.

Thanks very much, Francis - hadn't thought to check that. I'll see if I
can pursue this upstream. It appears we do have the latest version of
linbox (1.3.2).
