Comment (by darij):
Just had a quick look, but this confused me:
{{{
+ Reverse row bumping is only implemented for tableaux with
weakly increasing
+ and strictly increasing columns (though the tableau does not
need to be a
+ SemistandardTableau).
}}}
What is wrong about this? Isn't reverse row bumping only *defined* for
semistandard tableaux? Or do you have a generalization of it that is so
natural as to deserve the name "reverse row bumping" without any further
qualification?
In other news, thanks for this work! It's a thing that ought to have been
implemented long ago...
