I am confused about the interface between SkewTableaux and Tableaux. I suspect this is something people are aware of.
The points I have come across (and I doubt these are the only ones) are: A SkewTableau can be created from a chain of partitions using the keyword chain. This does not work for Tableau. There is a work around: given a chain of partitions which starts with the empty partition, create the skew tableau using the chain keyword, convert to a list, use this to construct a tableau. Evacuation and promotion are not defined for skew tableaux. Is this because the definition does not make sense or because no-one has yet included them? Mathematically, a tableau is a skew tableau with empty inner shape. Many (most?) methods make sense for skew tableaux. Ideally, these methods would be defined for skew tableaux and made available to straight tableaux. I don't know the appropriate mechanism for doing this in sage but I expect people have ideas or even plans on this. ...or this has been done already and I have missed it. -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
