Comment (by darij):
Sorry, but what does this mean:
{{{
496 def to_ncsym_on_basis(self, I):
497 r"""
498 The image of the basis element indexed by
``I`` under the
499 map to the symmetric functions in non-
commuting
500 variables that fixes the usual symmetric
functions.
}}}
How can a map from NSym to something fix the usual symmetric functions if
the latter aren't a subspace of NSym? (Same question for both
{{{to_ncsym}}} methods.)
Oooh, I think you mean "commutes with the projection onto the usual
symmetric functions". Maybe clarify this?
