Hi, This one looks really serious. In some ways seems to be computer dependent because my answers seem to have twice as many digits as yours. sage: Sym = SymmetricFunctions(QQ) sage: p = Sym.p() sage: s = Sym.s() sage: s(p[2,2]) s[1, 1, 1, 1] - s[2, 1, 1] + 2*s[2, 2] - s[3, 1] + s[4] sage: g = s

Hi Franco, Will this also happen on this person's computer with sage-5.3.rc0? I think I am running this on the same computer, but I do not have sage-5.0.1 installed any longer. sage: Sym = SymmetricFunctions(QQ) sage: p = Sym.powersum() sage: s = Sym.schur() sage: f = p([1,1,1,1,1,1,1,1,1,1,1])/9

Someone sent me the following sage session, which I cannot reproduce, but I'm asking whether this is a known issue and whether someone can reproduce it: sage: p=SFAPower(QQ) sage: s=SFASchur(QQ) sage: f = p([1,1,1,1,1,1,1,1,1,1,1])/990 + p([2,2,2,2,2,1])/10 + p([5,5,1])/10 - p([10,1])/10 + p([9,
