Comment (by zabrocki):
So I haven't the first clue about how to muck with the spkg's. Will you
post your fix? I haven't even been able to check that it corrects the
problems with the symmetric function calculations in sage. Essentially
there are two problems that need to be checked (or three if you count the
first issue that I provide a fix for above).
The first one is that at degree 36 the calculation is not correct.
The second one is that after a calculation at degree 47 the coefficients
start to become random.
