A linear ordering of the vertices of a graph G separates two edges of G if both the endpoints of one precede both the endpoints of the other in the order. We call two edges $$\{a,b\}$$ { a , b } and $$\{c,d\}$$ { c , d } of G strongly independent if the set of endpoints $$\{a,b,c,d\}$$ { a , b , c , d } induces a $$2K_2$$ 2 K 2 in G. The induced separation(More)
