+1 to this comment of Volker. And the notation should be "^" (hat) I had Darij's problem as well, and many others probably did as well. In a right action, I would prefer p(1) to give a warning. In a right action, I would want some notation where p is on the right, preferably 1^p (1 hat p). The notation "*" has the wrong distributive laws in case of actions on rings or groups. Of course this is irrelevant for permutations acting on sets, but since Galois groups can be interpreted as permutation groups too and they act on rings, the hat is much better. +1 also to a parent option for all groups with natural actions (Galois groups, permutation groups, ...?) saying "left" or "right". I don't care too much what the default value is in each case, as long as there are warnings. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
