Induced Saturation of $P_{6}$

Abstract

A graph GG is called HH-induced-saturated if GG does not contain an induced copy of HH, but removing any edge from GG creates an induced copy of HH and adding any edge of GcG^{c} to GG creates an induced copy of HH. Martin and Smith showed that there does not exist a P4P_{4}-induced-saturated graph, where P4P_{4} is the path on 4 vertices. Axenovich and Csik\'os studied related questions, and asked if there exists a PnP_{n}-induced-saturated graph for any n5n\geq5. Our aim in this short note is to show that there exists a P6P_{6}-induced-saturated graph.
