Comment (by andrew.mathas):
Replying to [comment:9 tscrim]:
> There are also duplicates in the `"down"` iteration. For this, I think
we should just use the crystal iteration from #15584, which seems to
match. Do you agree?
Great. I noticed that I had too many tuples yesterday but didn't have time
to investigate. I thought that I just needed to add the direction to the
calls to the good nodes routines in order to get the labelling that you
are using but, in addition, I should have changed `cell<=c` to `cell>=c`.
With this fix to the code our labellings agree. I also separated the four
different iterations (for up/down and level 1/higher levels) into their
own methods.
With these changes in place the timing for my code are:
{{{
sage: %timeit KleshchevPartitions(5,[3,2,1],3)[:]
100 loops, best of 3: 6.44 ms per loop
sage: %timeit KleshchevPartitions(5,[3,2,1],3, direction="down")[:]
100 loops, best of 3: 6.62 ms per loop
}}}
Mind you I am not sure how meaningful this is as there is probably some
caching going on with `UniqueRepresentation`...
