    Bertfried Fauser kindly created and/or expanded Young diagram

  2. I've written xy-pic codes for the two diagrams on Young diagram, but do not know how to put them on the page (codecogs seems not to work with \begin{xy}..\end{xy}). here are the codes in case anyone is able to make them work on the nLab page:

    \begin{xy}
    ,(0,0);(25,0)**\dir{-}
    ,(0,-5);(25,-5)**\dir{-}
    ,(0,-10);(20,-10)**\dir{-}
    ,(0,-15);(20,-15)**\dir{-}
    ,(0,-20);(10,-20)**\dir{-}
    ,(0,-25);(5,-25)**\dir{-}
    ,(0,-30);(5,-30)**\dir{-}
    ,(0,0);(0,-30)**\dir{-}
    ,(5,0);(5,-30)**\dir{-}
    ,(10,0);(10,-20)**\dir{-}
    ,(15,0);(15,-15)**\dir{-}
    ,(20,0);(20,-15)**\dir{-}
    ,(25,0);(25,-5)**\dir{-}
    \end{xy}



    \begin{xy}
    ,(15,0);(25,0)**\dir{-}
    ,(15,-5);(25,-5)**\dir{-}
    ,(10,-10);(20,-10)**\dir{-}
    ,(5,-15);(20,-15)**\dir{-}
    ,(0,-20);(10,-20)**\dir{-}
    ,(0,-25);(5,-25)**\dir{-}
    ,(0,-30);(5,-30)**\dir{-}
    ,(0,-20);(0,-30)**\dir{-}
    ,(5,-15);(5,-30)**\dir{-}
    ,(10,-10);(10,-20)**\dir{-}
    ,(15,0);(15,-15)**\dir{-}
    ,(20,0);(20,-15)**\dir{-}
    ,(25,0);(25,-5)**\dir{-}
    \end{xy}
  3. used SVG now :)

    Thasnks, very nice. Details on how to use xypic graphics is at HowTo. But I suppose SVG is preferred over that method here anyway.

  5. Thanks. And the SVG method is so preferred that Anonymous Coward has greatly improved my original rendition by adding colors and very light lines to show the cancelled diagram!

    as far as concerns the use of xy, it seems that codecogs accepts the \xymatrix command, but not more general xy commands. But that's over, I'm converted to SVG now :-)

    But codecogs should also generate SVG output. On my computer I can generate gif etc. outputs from them but not SVG. I can use the SVG creator of course, but somewhat hand-created random allignement makes me a bit unconformtable. It seems for content-full entries one should create a separate entry for a big chunk of SVG code and then include it as one can in general include code from another entry. Otherwise the SVG code takes pages and then the content part is hard to find and easy to loose by error when inserting and deleting long SVG paragraphs.

    I added four more things that are classified by Young diagrams.
