Thanks for your workaround this yet another empty partition bug in
Symmetrica!
Here is an (untested) code-duplication free variant with an
explanation:
if x[0]==[] and x[1]==[]:
# Workaround empty skew partition bug in Symmetrica (see #12140)
x = [[1],[1]]
skewschur = symmetrica.part_part_skewschur(x[0], x[1])
Also, please add an appropriate doctest. Since this change is very
localized, I doubt it will conflict with anything in the Sage-Combinat
queue. So you can just post it on trac, and I'll finish the review
there.
Cheers,
Nicolas
