Hi all (Travis in particular since he's working on the file),
A few days ago, the lack of functionality in combinat/skew_tableau.py
(as opposed to combinat/tableau.py) bit me: I was trying to generate
all skew semistandard tableaux of a given shape with a given
max_entry, and noticed that there

Hey Darij and everyone,
You are correct, it is just a restructuring of skew* and
ribbon[shaped](tableaux) to follow the category framework and better naming
conventions. #14101 and its dependency #14772 and possibly #14519 are
basically done; although #14101 still actually has some work
I believe Mike will do the full review of #14772. Arthur and I are
planning on cross reviewing #14101.
To clarify, it is Mike Hanson.

I have already posted the following question to the Maxima mailing list [1],
but I am not sure whether corresponding improvements should go into Sage or
Maxima.

Hi all,
Following RJF's suggestion, I played around with Maxima for a little while
to see where the problem arises. As far as I can tell, this is again a
problem with the fact that simplify_radical gets called in simplify_full
(see #12737). The problem that I'm seeing used to be absent when
Hi Dox,
In addition to the link that Leif provided, it would be good to open a
ticket on trac first with a description of the changes you propose to make.
Let me know if you need any further help. I'd be happy to review your patch
when you're done.
All the best,
Joris

H.. A long time ago I wrote a very nasty patch that prevented one
from building a Permutation on any set which was not 1, ..., n because
I got angry at the fact that many methods of Permutations
Looks like the code that you
change does not come from the same patch, but it looks to me that if a
PermutationGroup handles both 1, ...,n and a, b, c as its
elements, then I expect that it should handle 0, 1, 2 as it handles
a, b, c, that it to say probably with labels, and an internal
This is exactly what the patch I posted does.

Yeah. Right.
Just lost another occasion to keep quiet :-P

Hi,
i first want to say that i love you all, i am not deeply involved in
sage-graphs nor sage-combinat, nor representing any community. Just my
two cents about this thread and the related tickets.
- I disagree that this thread reached a consensus.
- I disagree that functionalities in Sage can

This makes an assumption in Maxima, where most of the symbolic algebra
takes place.
sage: u = var('u', domain='real')
This sets a flag in pynac, which does nothing as far as I can tell.

There is certainly an opportunity to write a program that works like this:
