Heptagonal numbers are numbers that have the form for all .Consider the graph G with p vertices and q edges. Assume that is an injective function with being the heptagonal number. Define such that for all edges .If is a sequence of distinct sequential numbers then the function is said to have heptagonal graceful labeling and the graph admitting such a labeling is termed as heptagonal graceful graph. This work investigates heptagonal graceful labeling of various graphs.
