Abstract

It is known that for all sufficiently large s, there are at least \documentclass{article}\footskip=0pc\pagestyle{empty}\begin{document}$(\frac{5}{3})$\end{document}^2__s__^ nonequivalent graceful labellings of the path on 2__s__ + 1 vertices. Using this result, we construct exponentially many index one current graphs with current group ℤ~12__s__ + 7~ such that many of the current graphs have different underlying graphs. The constructed current graphs for all sufficiently large s__generate at least 30^s^ nonisomorphic triangular embeddings of K~12__s + 7~. © 2009 Wiley Periodicals, Inc.
