1. Are the matrices in these tests dense?
2. How do the timings grow with the dimension?

Posting a reply to repay all the help Ive received from the Sage
folk.
Im a software guy more than a math guy and no Sage expert but
hopefully this is accurate.

Yes, very.

I do not know.

This is for the combinat folks:
sage: from sage.combinat.permutation import to_standard as pts
sage: a = [1,2,4]
sage: pts(a)
[1, 2, 3]
sage: a
[5, 5, 5]
Is this desired behavior? It seems quite dangerous. I think I've
found a workaround for me, but at the very least shouldn't this be
documente
This is perhaps related, but I found that using one-line permutation
notation is rather dangerous. It would be nice to have some more input
checking here, perhaps with an optional check=True argument to switch it off
if you have to:
sage: Permutation([3,2]) # invalid one-line notation
[3, 2]

This is now ticket #11421.

Hi all,
I have a bit of trouble with sage-gdb in 4.7.1.alpha1, after sourcing sage-env
I get this this starting sage-gdb:
../local/bin/sage-gdb
/home/work/fbissey/sandbox/sage-4.7.1.alpha1/local/bin/sage-ipython

Sorry I got the ticket number wrong somehow. I meant #10469 as
a potential culprit for my sage-gdb problems.
