I try the following codes, but it does not work.
SF= SymmetricFunctions(QQ)
s=SF.s()
I=P.incidence_algebra(SF)
s([2,1])*I[1,1]
TypeError: unsupported operand parent(s) for *: 'Symmetric Functions over Rational Field in the Schur basis' and 'Incidence algebra of Finite lattice containing 4 elements over Symmetric Functions over Rational Field'
