The action of a translation on a point provides a point that is denoted . This action satisfiesNote: The second in the left-hand side is a vector addition; each other denotes an action of a vector on a point. This notation is not ambiguous, as, to distinguish between the two meanings of , it suffices to look at the nature of its left argument.
