Do somebody knows if in M exist operations dealing with lattices [ http://mathworld.wolfram.com/Lattice.html ]? I am specifically interested in the possibility to feed a graph representing a poset [ http://mathworld.wolfram.com/PartiallyOrderedSet.html ] to a function, and this function should return True if a poset is also a lattice. ... I hope it isnt asking too much! thanks for any info. Alessandro Magni
