Great. To install the patch, download it by going to http://trac.sagemath.org/sage_trac/ticket/9838 Click on the patch trac_9838.patch which will bring it up. Go to the bottom of the page and click original_format to download it. Now you have a copy of the patch locally. Go to your sage root directory, which I will call $SAGE_ROOT and issue the following commands: cd devel sage -b main sage -clone 9838 This will create a clone of sage called sage-9838. Now you will need mercurial installed. For example if you have Ubuntu you can run sudo apt-get install mercurial if you do not have it already. You are in the directory $SAGE_ROOT/devel. cd sage-9838 hg import [path to trac_9838.patch] sage -b When this is done, you have a patched version of sage. You can switch back and forth between the old version sage-main and sage-9838 using sage -b main sage -b 9838 When you load sage you should see this: Loading Sage library. Current Mercurial branch is: 9838 sage: R.<q> = ZZ[] sage: KG2 = WeylCharacterRing("G2", base_ring = R, style="coroots") sage: KG2(q) q*G2(0,0) sage: chi=(q+1)*KG2(1,0) sage: chi^2 (q^2+2*q+1)*G2(0,0) + (q^2+2*q+1)*G2(1,0) + (q^2+2*q+1)*G2(0,1) + (q^2+2*q+1)*G2(2,0) Dan -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
