Problem: can anyone please help me understand (and interpret) slide 35 ?? It is extremely frustrating to have succeeded in reconstructing all slides sofar into Mathematica-one-liners (or abouts), cfr http://users.telenet.be/Wouter.Meeussen/NekrasovOkounkov.nb but I'm completely at a loss with this one. Some examples would work wonders for me. Like, what is the result on lhs\rhs partitions\permutations of n=4? And, to make things worse, it's labeled "the Fundamental tool".
