On the Circumference of 3-Connected Cubic Triangle-Free Plane Graphs
The circumference of a graph G is the length of a longest cycle in G, denoted by cirG. For any even number n, let cn = min {cirG|G is a 3-connected cubic triangle-free plane graph with n vertices}. In this paper, we show that an upper bound of cn is n+1−3⌊n/136⌋ for n≥136.
