Comment (by andrew.mathas):
Regarding the lexicographic ordering, I disagree with Stanley and always
call this the lexicographic ordering. By definition, the lexicographic
ordering on partitions should be the "dictionary ordering" where the parts
of the partitions are read from left to right and the "letters" are
ordered naturally with 1<2<3<.... Hence, for partitions of 5 we have
{{{
(1,1,1,1,1)<(2,1,1,1)<(2,2,1)<(3,1,1)<(3,2)<(4,1)<(5)
}}}
I think that this is the more common usage. In any case, given Stanley, it
seems that both definitions are used so it would be enough in the
documentation to state clearly which convention sage uses and perhaps add
a warning the sage convention disagrees with the other ordering.
