Fig. 11
Left - Illustration of the 2 and 3-closures. The 2-closure of link (6,a,b) is equal to 4 since we have to go back to t=2 to find a reversed link (2,b,a). The 3-closure of link (6,a,b) is equal to 5 since we have to go back to t=1 to close the triangle composed of (6,a,b),(4,b,d),(1,d,a). Right - The distribution of 2- and 3-closures for all links in \(\mathcal {C}\) and \( \mathcal {T}_{MM} \). Note that we only consider links with finite k-closures, links with infinite values being ignored
