run

sage: S = ShiftingOperatorAlgebra()
sage: Sym = SymmetricFunctions(ZZ)
sage: s = Sym.schur()
sage: S[2, 1](s[4, 3, 2, 1])

and see what happens

Well, but this is solved by

sage: S = ShiftingOperatorAlgebra(ZZ)
sage: Sym = SymmetricFunctions(ZZ)
sage: s = Sym.schur()
sage: S[2,1](s[4,3,2,1])
s[6, 4, 2, 1]

Yes, the shifting operator and the schur function need to be constructed over the same ring.

Otherwise the shifting operator can't act on the schur function.

Thanks George!

It kindof sucks though that it doesn't work for subrings.
