Given a graph , another graph is -saturated if does not contain a (not necessarily induced) copy of , but adding any edge to it does. The function s a t ( n , H ) {\displaystyle sat(n,H)} is the minimum number of edges an H {\displaystyle H} -saturated graph G {\displaystyle G} on n {\displaystyle n} vertices can have.
