Connecting cominrule.v0.1.txt and Schubert.v0.1.txt (both available at http://www.math.umn.edu/~ayong/papers.html) -------------------------------------------------------------- The reader of "A combinatorial rule for (co)miniscule Schubert calculus" might be interested in how to computer check the rule given in that paper using the two Maple packages stated above. (The proof itself is _not_ by computer.) Let me describe a quick translation in types E6, E7: 65431 542 243 65431 7 6 5 24 76543 65431 542 243 765431 These are labellings of the boxes of \Lambda_{E6} and \Lambda_{E7} respectively. Given a shape in one of these two posets, the associated reduced word is obtained by reading the rows right to left and top down. For example X XXX XXXXXX in the latter poset corresponds to [5,3,4,2,1,3,4,5,6,7], which then can be used in Schubert.v0.1.txt. Naturally, cominrule.v0.1.txt is much faster than Schubert.v0.1.txt, in the cases that it handles. This is mainly due to the fact that even if the input of Knutson's algorithm used in Schubert.v0.1.txt begins with cominuscule data, the recursion passes through all of the Weyl group.
