smc user reported these inconsistencies related to listing monomials of a
symmetric function:
{{{
e = SymmetricFunctions(SR).e()
f = e([2]).expand(3)
f
f.monomials()
f.lt()
x0*x1 + x0*x2 + x1*x2
[1]
x0*x1 + x0*x2 + x1*x2
}}}
i.e. just `[1]` and the whole polynomial, while over `QQ`:
{{{
e = SymmetricFunctions(QQ).e()
f = e([2]).expand(3)
f
f.monomials()
f.lt()
x0*x1 + x0*x2 + x1*x2
[x0*x1, x0*x2, x1*x2]
x0*x1
}}}
lists all three monomials and only one term for `lt()`.
