The action is called free (or semiregular or fixed-point free) if the statement that = for some already implies that =. In other words, no non-trivial element of fixes a point of . This is a much stronger property than faithfulness. See more In mathematics, a group action on a space is a group homomorphism of a given group into the group of transformations of the space.
