Motif examples. F, the transitive triangle (triad 030T) is not a special case of H, the out-star (triad 021D), when considered as motifs (or triad census classes): they are distinct induced subgraphs of three nodes. However, when considered as ERGM configurations, since H is a subgraph (but not an induced subgraph) of F (the transitive triangle is formed by “closing” the out-star with an additional arc), in their corresponding statistics both F and H are counted for an occurrence of F
