I would say the opposite: Tableau should inherit from SkewTableau since every tableau is also a skew tableau, but not vice versa.

Re: [sage-combinat-devel] Re: strange convention for column words of (skew) tableaux
I agree that the two methods should not have the same name. My suggestion: deprecate one and call it 'to_word_by_column_reverse' (although it seems weird to bother to include both). Can SkewTableau inherit from Tableau and have 'to_word_by_column' there? -Mike On Monday, 28 November 2016 19:05:48 UTC-5, Andrew wrote: > > Yes they should definitely be consistent -- sorry, I misread your email > and thought that you wanted the method for skew tableau to be the reverse > of that for tableauxnot enough coffee (or maybe too much:). > > As it currently stands there are many independent tableaux classes. > Ideally, methods like this should live in a common base class so > consistency is enforced and we don't re-implement them in each class. > > Andrew > > On Tuesday, 29 November 2016 09:33:52 UTC+11, Anne Schilling wrote: >> >> Hi Andrew, >> >> If someone had just copied the code from Tableaux to SkewTableaux, >> then at least it would be consistent.

Re: [sage-combinat-devel] Re: strange convention for column words of (skew) tableaux
Hi Andrew, If someone had just copied the code from Tableaux to SkewTableaux, then at least it would be consistent. I think it is really bad, if a method changes convention with a parent, given that one could be a subclass of the other.

[sage-combinat-devel] Re: strange convention for column words of (skew) tableaux
Hi Anne, One of the problems with tableaux is that almost every possible variation of any definition is used by some one. With this in mind we probably should implement variations whenever possible. I don't know anything about the history of this particular method (git blame might help), but I suspect that some one just copied the code from tableaux to skew tableaux. I certainly have no objection either way as I don't use this method.
