Hi Dan, I've been spending a bit of time with symmetric functions recently. In the near future, I'll be making a commit that adds support for Hall-Littlewood, Macdonald polynomials, and quasisymmetric functions. Other stuff that will need to be done are LLT polynomials, k-Schur functions, and noncommutative symmetric functions.
Also, there isn't any support for tree-like structures. I think that implementing combinatorial species, while taking a fair amount of initial work, would be the best way to go about this. I've started porting Aldor-Combinat over to Sage, but that's still in the early stages. There are also quite a few other things from the MuPAD-Combinat that would be good to have in Sage. Let me know if any of these things sound interesting to you. --Mike On Nov 29, 2007 7:43 PM, Dan Drake <[EMAIL PROTECTED]> wrote: > > By the way, what other sorts of combinatorial functions need to be > written?
