Let G be a (p,q) graph. A mapping f : V (G) ? {0, 1, 2} is called 3-product cordial labeling if |v????(i) ? v???? (j)| ? 1 and |e???? (i) ? e???? (j)| ? 1 for any i, j ? {0, 1, 2},where v???? (i) denotes the number of vertices labeled with i, e???? (i) denotes the number of edges xy with ????(x)????(y) ? i(mod3). A graph with 3-product cordial labeling is called 3-product cordial graph. In this paper we investigate the 3-product cordial behavior of alternate triangular snake, double alternate triangular snake and triangular snake graphs.References
