On Set-Indexers of Paths, cycles and certain Related Graphs

In this paper, we mainly obtain the set-indexing number of paths and certain cycles. For a given cycle, we show that there are only two possible values for the set-indexing number of it. We have also computed the set-indexing number of fans of order atleast five. Finally we study the set-indexers of certain wheels, suns and helms and derive the set-indexing numbers of the same.
