The ERC and NRD of the multiplex networks. (a) Three layers of the multiplex networks. (b) The synthetic network of the multiplex networks in (a). We combine these three networks into one network by adding an edge between two nodes if there is any edge between them in one of the three networks. (c) The ERC of the multiplex networks in (a). Edge (1,6) appears three times with the repeated number of two in the multiplex networks. Therefore, the ERC of edge (1, 6) is 2. (d) The NRD of the multiplex networks in (a). Node 1 has a 2-order NRD that is equal to 1 because there is one edge (1, 6) whose ERC is equal to 2 that is connected with node 1.
