Abstract
A graf called odd graceful graph if there is an injectivemapping f:V(G)→{0,1,2,…,2q-1} such that for each edge xy∈E(G) labeled by |f(u)-f(v)|, and the results willform a label on the edge {1,3,5,…,2q-1} which is bijective. Variabel q is the number of edges. This paper purpose is to construct the formula of odd graceful labelling on the ilalang graph (S_n,3) and it-s variation.
