[sage-combinat-devel] Re: The reading tableau of a partition
Hi Travis, What confused me is that the example in the documentation seems to say that the reading tableau for the *partition* (3,2,1) should be 1 4 6 2 5 3 whereas the example in the doc-test says that it is 1 3 6 2 5 4 These two tableaux are different. I need the first of these tableaux and I thought that this is what reading_tableau() was supposed to return. This isn't a big deal for me because I can get this tableau easily a different way. All these concerns aside, however, I am still confused by the documentation as it the example contained in the help for reading_tableau seems to contradict what the function actually does. Notice that this a method for a partition which returns a tableau -- there are no permutations in sight here.

Hi Nicolas, Cool! Thank you for setting this up! This will be immensely useful to let people try out code who are not (yet) developers! Cheers, Anne On 4/12/13 1:19 PM, Nicolas M.

[sage-combinat-devel] Sage notebook server with combinat patches installed
Dear Sage developers, On https://combinat.sagemath.org:8080/ You will find a publicly accessible notebook server running with the Sage-Combinat patches applied. Main use cases: giving access to colleagues to your in-development code. As the front page says, it's still pretty experimental. In particular Sage and Sage-Combinat are updated manually ... when I get to do it ... I'll advertise it more widely (in particular on the wiki) when we will have beta tested it more. Fell free to volunteer to take over the maintenance! Cheers, Nicolas -- Nicolas M.

Re: [sage-combinat-devel] Re: The reading tableau of a partition
Travis, Any reasonable definition of reading word of tableau will have the property that the result of inserting the reading word of the tableau, is the original tableau.

The documentation is describing the tableau T, which then it takes the reading word (which is [3, 2, 5, 1, 4, 6]), and then runs RSK on that permutation and pulls the reading tableau. While the documentation is not the best, it is accurate (I had to read it a few times myself).
