    The above lists all summands of order 6 or lower (i.e. those containing 6 or fewer X 's and Y 's). The X ↔ Y (anti-)/symmetry in alternating orders of the expansion, follows from Z(Y, X) = −Z(−X, −Y). A complete elementary proof of this formula can be found in the article on the derivative of the exponential map.
