Graph Theory International audience A graph is extended P4-laden if each of its induced subgraphs with at most six vertices that contains more than two induced P4's is 2K2,C4-free. A cycle transversal (or feedback vertex set) of a graph G is a subset T ⊆ V (G) such that T ∩ V (C) 6= ∅ for every cycle C of G; if, in addition, T is a clique, then T is a clique cycle transversal (cct). Finding a cct in a graph G is equivalent to partitioning V (G) into subsets C and F such that C induces a<span class="external-identifiers"> <a target="_blank" rel="external noopener noreferrer" href="https://doi.org/10.46298/dmtcs.616">doi:10.46298/dmtcs.616</a> <a target="_blank" rel="external noopener" href="https://fatcat.wiki/release/o4tvg27uvjcnpaxizvwqsuqje4">fatcat:o4tvg27uvjcnpaxizvwqsuqje4</a> </span>
