Erratum: a Little Emendation to the Graceful Labelling of the Generalised Petersen Graph $P_{8t,3}$ when $t=5$

Abstract

The proof of gracefulness for the Generalised Petersen Graph $P_{8t,3}$ for every $t\ge 1$, written by the same author (Graceful labellings for an infinite class of generalised Petersen graphs, Ars Combinatoria $81(2006)$, pp. $247-255)$, requires the change of just one label, for the only case $t=5$.
