f : V U E -> (1,2, ...,k) of a graph G is a totally irregular total k-labeling if for any two different vertices x and y of G, their weights w(x) and w(y) are distinct and for any two different edges xy and uv of G, their weights w(xy) and w(uv) are distinct, where the weight w(x) of a vertex x is the sum of the label of x and the labels of all edges incident with x, and the weight w(xy) of an edge xy is the sum of the label of edge xy and the labels of vertices x and y. The minimum k for which a graph G has a totally irregular total k-labeling is called the total irregularity strength of G, denoted by ts(G). In this paper, we determine <br />
