[sage-combinat-devel] Re: error with skew Schur functions

2012-05-07 Thread Mike Zabrocki
Just an update on this bug.
there is a fix now in:
trac_12140_skewschurfix-mz.patch

Florent helped me put together a patch and this was pushed onto
the sage combinat queue that fixes symmetrica.part_part_skewschur

The plan is that Anne will use the patch in her demonstration tomorrow.

 Why is this test not put into symmetrica.part_part_skewschur? It seems
 odd to test it before calling, because this kind of tests would then
 certainly also be necessary in other places.
