Comment(by ncohen):
Excellent !!! Well, could you send your code as a patch to replace mine
then, as it does not use LP ? :-)
two remarks though :
* Perhaps "slider" could be defined inside the gale_ryser function,
except if it can be useful in other parts of Sage
* The order defined on the partitions is equivalent to the the
function "dominates" in the Partition class.. In my patch it was written
as p2.conjugate().dominates(p1), so it may not be necessary to rewrite it
Great work !! :-)
