Abstract
Some problems concerning the stability index of the permutation graph (Pn, π) are investigated. It is shown that for a certain class of permutation graphs, called Roman numerals, the stability index can be only 2n, 2n − 4, 2n − 5, 2n − 6 or 2n − 7. The general situation for (Pn, π) is more complicated and some open questions are listed.
