Abstract

Odd graceful labelings of a graph are a variation of a graceful labeling. In each, the vertices are uniquely labeled with integers, and edges are assigned the difference between the incident vertex labels. For a graph with m edges, the goal of a graceful labeling is to have distinct edge labels 1 to m, while an odd graceful labeling has odd edge labels from 1 to 2m−1. In this paper we construct odd graceful labelings of prism graphs, denoted Cn×P2, when n is even using the cases of n = 6k,6k+2, and 6k+4, which require similar but altered labelings.
