Odd Graceful Labeling of the Revised Friendship Graphs
Elsayed Metwalli Badr · 2013
The aim of this paper is to present some odd graceful graphs. In particular we show that the revised friendship graphs F(kC 4), F(kC 8), F(kC 12), F(kC 16) and F(kC 20) are odd graceful where k is any positive integer. Finally, we introduce a new conjecture " The revised friendship graph F(kC n) is odd graceful where k is any positive integer and n = 0 (mod 4).
