Abstract

Pavel Hrnciar and Alfonz Havier \([6]\) introduced a clever idea of transferring labeled pendant edges incident at a vertex of a graceful tree to some other suitable vertex of that tree, so that another graceful tree is obtained. This idea is further explored in this paper to generate graceful lobsters from a graceful caterpillar with \( n \) edges.
