Ok; out of curiosity, why do you need the relabelled poset for? > > The elements of L would simply be represented as plain lists. See: > What would be the advantage of this? No need for a linear extension class. No need for coercing/converting them back and forth. But any operation needs to go through the parent (L.blah(l) instead of l.blah()). Which approach is more natural depends much on the context (like when we write down mathematics), which is why we support both. At the end, all I can recommend is to listen to the code; it will tell you. Cheers, Nicolas -- Nicolas M.
