A graph is-free if it contains no induced subgraph isomorphic to the pathon eight vertices. In 1995, Erdős and Gyárfás conjectured that every graph of minimum degree at least three contains a cycle whose length is a power of two. In this paper, we confirm the conjecture for-free graphs by showing that there exists a cycle of length four or eight in every-free graph with minimum degree at least three.
