Christian and Nicolas, Is the following a decent way to determine whether "element" is an element of a Weyl group of a given Cartan type?
hasattr(element, "domain") and hasattr(element.domain(), "cartan_type") and element.domain().cartan_type() == cartan_type E.g. is this likely to change or are there subclasses of WeylGroups that don't have the domain attribute? --Mark -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
