Replying to [comment:47 lftabera]:
> I got the same error in permgroup.py in both 32 and 64 bits. I got the
permutation (1,2)(4,5) in two different machines with 4.6 + patches from
this ticket.
Really strange.
> We can investigate further what is going on, but I do not like this kind
of tests against random_element. Even if we use the same seed.
Well, we ''do'' use the same seed. So, it has to be reproducible.

I guess there is currently a related discussion at
[http://groups.google.com/group/sage-
devel/browse_thread/thread/c201930abdbd23d3 sage-devel]
> About the errors in number_field all tests passes in 64 bits but I get
the same errors as John in 32 bits. Concerning selmer group. Are both
results right or only one of them?
Both are right. The method is supposed to return ''a'' generating set. And
that is the case for both answers. And in the original version, the
expected answer did depend on 32- versus 64-bit.
Best regards,
Simon
