a, Breakdown of interaction information in individual graph motifs. b, Subgraphs with positive and negative contribution to the information for each motif. Red and blue edges in each graph correspond to information-enhancing and information-limiting pairwise interactions, respectively. c, Left, in the two-pool model, the network consists of two different pools of interactions, each of which has a different distribution of information-enhancing and information-limiting. Right, three possible ways of building a ‘+,+,+’ triplet, with their probabilities are shown. d, Probability weights presented in equation (47), as given in Supplementary Note, for open triplets (left box), closed triplets (middle box), and quadruplets (right box) for different network sizes (each column is one network size) and different \(\delta P=P\left(+\right)-P\left(-\right)\) (upper row: \(P\left(+\right)-P\left(-\right)=0.1\), middle row: \(P\left(+\right)-P\left(-\right)=0\), lower row: \(P\left(+\right)-P\left(-\right)=-0.1\)).
