| The locating rainbow connection number of a graph is defined as the minimum number of colors required to color vertices such that for every two vertices there exists a rainbow vertex path and every vertex has a distinct rainbow code. This rainbow code signifies a distance between vertices within a given set of colors in a graph. This paper aims to determine the locating rainbow connection number for vertex-transitive graphs. Three main theorems are derived, focusing on the locating rainbow connection number for cycles, $(n-2)$-regular graphs, and complement of cycles $\overline{C_n}$. | ||
