 For the ring lattice the clustering coefficient formula_39, and so tends to formula_40 as formula_3 grows, independently of the system size.In the limiting case of formula_35 the clustering coefficient is of the same order as the clustering coefficient for classical random graphs, formula_43 and is thus inversely proportional to the system size.In the intermediate region the clustering coefficient remains quite close to its value for the regular lattice, and only falls at relatively high formula_1.
