Abstract
For , we prove that the minimum number of triangles in an -vertex -saturated graph with minimum degree 4 is exactly , and that there is a unique extremal graph. This is a triangle version of a result of Alon, Erd\H{o}s, Holzman, and Krivelevich from 1996. Additionally, we show that for any and , there is a -saturated -vertex graph with minimum degree that has copies of . This shows that unlike the number of edges, the number of 's () in a -saturated graph is not forced to grow with the minimum degree, except for possibly in lower order terms.
