[sage-devel] graded Hilbert series

Hello For anyone who is interested in weighted Hilbert Series, as opposed to "mere" standard Hilbert Series, I have what *should* be a very easy patch to review in ticket #17298. Ordinarily, I wouldn't draw anyone's attention to it, but this is my first time uploading a patch via git, and the

Try to build Sage from source. You most likely don't have the command line tools installed. Run "xcode-select --install" on the command line. On Wednesday, November 5, 2014 4:34:08 PM UTC, Qi wrote: > > Hello everyone, > > I'm new to sage and have just installed sage-6.3 on my mac osx 10.10.

At one point there was a branch trac/public/combinat/zabrocki/fixstrongtableaux/17252. This one has since been deleted. A new branch trac/public/combinat/zabrocki/fixstrongtableaux has been created. The two branch names conflict, you can't have a branch as a "subdirectory" of another branch.
