2018-11-14 19:02:48 +0200	commented answer	Rename Lambda in weight space Great, thanks! It's at least more elegant than overwriting `__str__`.
2018-11-14 15:53:24 +0200	asked a question	Rename Lambda in weight space It's a basic question, but after looking at the manual for a while I couldn't find the answer, so here goes. `R = RootSystem(["A",7]) print R.weight_lattice().fundamental_weight(1)` returns `Lambda[1]`. Is it possible to rename Lambda here? I could hack this by overriding the `.__str__` method, but is there a cleaner method?
2018-11-12 10:35:10 +0200	commented answer	Are subtypes of Cartan types implemented correctly? Thanks! We'll just work around it for now, maybe I'll have a go at improving Sage in the future.

2018-11-06 17:01:22 +0200	asked a question	Are subtypes of Cartan types implemented correctly? Consider the following code `CartanType("B3").subtype([2, 3]).index_set() CartanType("B3").subtype([1, 3]).index_set()` It gives `(2, 3) (1, 2)` in Sage 8.4. Is it wrong to expect the index set of a subtype to be the subset used in defining the subtype? From my point of view this inconsistency leads to all kinds of unexpected behaviour in the relabellings for subtypes, but maybe it is intentional?
