Rainbow connection number of a connected graph G is the minimum number of colors needed to color the edges of G, so that every pair of vertices is connected by at least one path whose edges have distinct colors. In this paper, we propose an upper bound to the size of the rainbow connection number in Recursive Transpose-Connected 4-Cycles (RTCC) pyramids.
