[sage-devel] Collecting ideas for posets

2015-06-21 Thread Jori Mäntysalo
How should ideas about posets and lattices be collected? (In general: about some topic X on Sage.) For example there should be a function to check if a poset is series-parallel composable, a function to see if a lattice is vertically indecomposable, an iterator over distributive lattices... An
