Let $G=(V, E)$ be a graph without isolated vertices. A subset $D \subseteq V$ is triple effect dominating set, if every vertex in $D$ dominates exactly three vertices of $V-D$. The triple effect domination number $\gamma_{t e}(G)$ is the minimum cardinality over all triple effect dominating sets in $G$. In this paper, the triple effect domination number $\gamma_{t e}(G)$ is studied to be changing or not after adding or deleting edge or deleting vertex. Some conditions are putted on the graph to be affected or not with several results and examples. Then, the triple effect domination and its inverse is applied on several graphs obtained from complement, join and corona operations.
