I rebased this now on top of #1605. There seems to be a new test failure (I have the vague feeling that I once debugged this one already, apparently it...

This needs non-obvious changes in Hecke apparently (maybe these are already in https://github.com/thofma/Hecke.jl/pull/1522, I forgot). So this shouldn't be in the 0.46 breaking release.

I'll look into it. And yes, `standard_tableaux` currently produces a "big list" internally and then returns an iterator over that list. The big list version was implemented in JuLie, copied...

Thank you for reporting all this. I fixed some of these in #3860. I don't think we can do anything about `filter(..., partitions(3))`. From what I understand, `filter` works on...

It is quite possible that there is a silent assumption in the tableaux code that any number one puts in is positive. This would also be what Fulton assumes in...
