A locating-total dominating set (LTDS) S of a graph G is a total dominating set S of G such that for every two vertices u and v in V(G) − S, N(u)∩S ≠ N(v)∩S. The locating-total domination number () l t G  is the minimum cardinality of a LTDS of G. A LTDS of cardinality () l t G  we call a () l t G -set. In this paper, we determine the locating-total(More)
