"Planar exact clique". Cette construction montre une notion de perfection pour la classe des graphes planaires : le plus petit nombre de sommets d’un graphe de maille impaire 2k+1, pour lequel il y a un homomorphisme de chaque graphe planaire de maille impaire 2k+1, est égal au nombre maximum de sommets, reliés par paires par des chemins de longueurs impaires et au plus de 2k-1.
