Hi Anne, Sorry for the slow response, but I realized there was a bit that I hadn't pushed to the combinat server yet (converting to symmetric functions). I've pushed now and the following should work: ---------------------------------------------------------------------- | Sage Version 4.6, Release Date: 2010-10-30 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- Loading Sage library.
