Hi!
I'd like to draw your attention to
https://groups.google.com/forum/?fromgroups#!topic/sage-devel/Ue5g73lN4KQ
The topic is: How to represent groups in Sage.
We would like to have an abstract group that is able to provide us with
different realisations of itself (permutation presentation,
I just wanted to test whether some experimental changes wouldn't break
anything and ran

I get quite a few failures, ugly errors, etc.
Which of these should I expect?

Hi Martin,
If you want to run tests on your own patch, I suggest to apply it to a clean
version of sage-5.2.rc0. All tests in a clean version of sage-5.2.rc0 should
pass! The ones that fail would then be due to your patch.
If you run sage -t on the sage-combinat queue, it is not guaranteed that

I am curious as to exactly what you did to get these doc test errors. Am I

Is it possible that your patch under positive review in the sage-combinat queue
trac_13243-new_methods_for_compositions-fs.patch

Dear sage developpers.
When I used the command region_plot,
I met some trouble.
I report the trouble.
After

I tried the following

I agree on both points :
(1) mixing things in the same glass sometimes gives unwanted results ;

I understand that from some point of view mixing groups and
their representations is a bad idea, but many groups are naturally
defined as transformation groups and using a matrix presentation
is just as natural as describing them by permutations, or even more so.

This is most likely a bug in GCC.
Could you try to install the package

This is to check whether using vanilla gcc-4.7.1 (as opposed to

Just a thought: it would be nice if we could somehow get hg blame to
annotate the file using Sage versions. Knowing that the line was changed
in changeset 17129 is useful, but what I *really* wanted to know was the
first released version of Sage (including alphas, beta, release
candidates)
Thanks everyone for your helpful posts, which came in overnight.
We have the classical groups (GL, SL,...) from GAP as groups of matrices
(in a natural way) and we have the projective versions (PGL, PSL,...) from
GAP as permutation groups. Testing indicates you cannot switch it around
