2016-07-01 20:39:25 +0200	asked a question	Getting hasse diagram of truncated young lattice Hi! So I compile the following code on sage cloud: `ord = lambda x,y: y.contains(x) def baseyoung(N): return [b for n in range(N) for b in Partitions(n)] view(Poset((baseyoung(5),ord)))` and it shows a hasse diagram of young diagrams. But whenever I compile it on sage in my laptop's terminal it gives the following error An error occurred.
