Assistant in Mathematics, Khajamian Higher Secondary School, Tiruchirappalli–620 020, Tamil Nadu, India Abstract A (p, q) connected graph is edge-odd graceful graph if there exists an injective map f: E(G) →{1, 3, …, 2 q-1} so that induced map f +: V(G) →{0, 1,2, 3, …, (2 k-1)}defined by f +(x) ≡Σ f ( xy) (mod 2 k), where the vertex x is incident with other vertex y and k = max { p , q} makes all the edges distinct and odd. In this article, the Edge odd gracefulne ss of Cartesian product of P 3 and C n is obtained. Keywords: Graceful Graphs, Edge-odd gracefu l labeling, Edge-odd Graceful Graph. Introduction A. Solairaju, A. Sasikala, C. Vimala [2008] got gracefulness of a spanning tree of the graph of product of P m and C n, A. Solairaju and K. Chitra [2009] obtained edge-odd graceful labeling of some graphs related to paths. A. Solairaju, C. Vimala, A.
