## Abstract We characterize all pairs of connected graphs {__X__, __Y__} such that each 3‐connected {__X__, __Y__}‐free graph is pancyclic. In particular, we show that if each of the graphs in such a pair {__X__, __Y__} has at least four vertices, then one of them is the claw __K__~1,3~, while the

We answer this question by determining the complete list of graphs that are not path graphs and are minimal with this property. Β© 2009
