* '''Direct Succession: x > y''' if and only if some relation x is directly following by y. In our example, we can consider that '''A > B''', '''A > E''', '''A > C.'''
* '''Causality: x → y''' iff x > y and not y > x. In our example, we can consider that '''A → E.'''
* '''Parallel: x || y''' iff x > y and y > x. In our example, we have '''B || C.'''
