Hi!
I just pushed on the Sage-Combinat queue a patch implementing edge
specific options for dot2tex drawing of graphs. It's experimental, and
I had to refactor a couple things (in particular the handling of edge
coloring). So in case this breaks anything for you, please let me
know; you
Dear Sage Devel Community,
Please send me an offlist email at wst...@gmail.com if you're very
interested in being invited to an upcoming Bug Days in Seattle, all
expenses paid. This will be a roughly 5 day workshop in which about 10-15
Sage developers gather to greatly improve the quality of
Hi,
Motivated by the call for the bug days, here is an idea to manage the
rapidly increasing number of new tickets on trac.
Many of the bugs on trac are
- duplicates,
- already fixed, which can be closed after adding a doctest or
- has not been seen by a developer who can fix it since
Nice, this worked perfectly..
Thanks.

Hi!
Burcin asked me to make a new version of ortho polys some time ago,
and since Ticket #9808 for upgrading numpy and scipy finally got a
positive review, I can now finish this task.
Please feel free to look at the new version. The new version is a lot
faster as the old implementation with
Hi, Burcin!
I think this is a great Idea!
I'm short on time in the next months, but
If I'm free again, could help with this.

Hello,
I am trying to define a matrix group generated by matrices over a
field which I have defined. At the moment, I am stuck with the the
question of how to make the base_ring an instance of CommutativeRing?
In particular, I get that the __init__ in free_module.pyc asks
isinstance(base_ring,

Yup, I see what you are talking about - e.g.
if (x.is_equal(_ex1)) // log(1) - 0
return _ex0;
Although it might be nice to stay relatively
What are you inheriting from? FreeModule is checking to see if you're
inheriting from sage.rings.commutative_ring.CommutativeRing. This was
written long before categories became available.

In addition to what David Roe said, if I remember correctly MatrixGroups in
Sage are implemented for matrices over finite fields. At some point I think it
calls GAP for the computations.
If your field is not finite, it might be better to use GAP directly
since Sage only
has infinite modular

No I don't - should I? Or is there another way to get around this?

This would be an infinite group which I think is not implemented in Sage or GAP.
I can't even imagine a way that GAP could help, but it can't hurt to
ask in the GAP support list. Maybe there is an approximation someone could
think of that might help. Please be as specific as possible when

You can either inherit from sage.rings.commutative_ring.CommutativeRing, or
modify FreeModule to work better with the category framework. The first is
probably the easier option.

Is there a reason you can't use finite cyclotomic fields? These exist in
Sage and are reasonably well optimized. And GAP supports matrix groups over
them, though as David Joyner mentioned, I don't think that functionality is
wrapped from Sage. Defining matrix groups over finite cyclotomic
Does this help?
sage: K = CyclotomicField(12) # 12 = 4*3
sage: K.gens()
(zeta12,)
sage: z = K.gens()[0]
sage: z
zeta12
sage: E3 = z^4
sage: E4 = z^3
sage: gens = [ matrix( K, 2, [ E3, 0, 0, E4 ] ), matrix( K, 2, [ -E3,
0, 0, -1 ] ) ]
sage: G = MatrixGroup( gens )
sage: G.order()

Cool. I'd be happy to review that after Wednesday (when I have an
application due). I can provide the perspective of someone who works mostly
within sage.rings rather than sage.combinat.
