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