Comment:
Some quick answers before I come to the real review.
It seems that it would be better to move methods in one commit and do
edits in another, for the sake of diff working sanely.
The sentence "f.inner_plethysm(g) is a polynomial in the coefficients of
g" meant to say that f.inner_plethysm(g) depends polynomially on the
coefficients of g. What I was trying to achieve there is to explain how to
compute inner plethysm outside of the homogeneous Schur-positive case.
This is also why I made that confusing linearity-in-distinct-degrees
claim. Your docstring seems much better, so I'm not wishing mine back.
