In particular, an action of a group on set of vectors, which stay vectors. Examples: * Permutation group of 3 elements on 3-vectors in obvious manner * Permutation group of 3 elements on 6-vectors in non-obvious manner where they are indexed [e,(12),(13),(23),(123),(132)] or something like that -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
