Re: [sage-combinat-devel] Symmetric functions --- HopfAlgebras(...) or not?

Hi Simon, The following is a problem for my work at #18758, which aims at making arithmetic operations faster that are defined via category element/parent classes: sage: Sym = SymmetricFunctions(FractionField(QQ['t'])) sage: ks3 = Sym.kschur(3) sage: ks5 = Sym.kschur(5)
