Consider a soldier facing in a given direction (say north). Let us denote "left face" by l, "right face" by r, "about face" by a, and "stand fast" by f. (The element f means "don't move from your present position." It does not mean "return to your original position.") Then we define and an operation middle;" /> meaning "followed by". Thus,  means "left face" followed by "left face" and is the same as the single "about face". Does the set H and operation  satisfy the commutative property?
?
