Let f (n) be the minimum number of cycles present in a 3-connected cubic graph on n vertices. In 1986, C. A. Barefoot, L. Clark, and R. Entringer (Congr. Numer. 53, 1986) showed that f (n) is subexponential and conjectured that f (n) is superpolynomial. We verify this by showing that, for n sufficie

Moon and Moser in 1963 conjectured that if G is a 3-connected planar graph on n vertices, then G contains a cycle of length at least OΓ°n log 3 2 Γ: In this paper, this conjecture is proved. In addition, the same result is proved for 3-connected graphs embeddable in the projective plane, or the torus
Jackson, B., H. Li and Y. Zhu, Dominating cycles in regular 3-connected graphs, Discrete Mathematics 102 (1992) 163-176. Let G be a 3-connected, k-regular graph on at most 4k vertices. We show that, for k > 63, every longest cycle of G is a dominating cycle. We conjecture that G is in fact hamilton
We show in this paper that for k Z-63, every 3-connected, k-regular simple graph on at most yk vertices is hamiltonian.

## Abstract In this article, we apply a cutting theorem of Thomassen to show that there is a function __f__: N β N such that if __G__ is a 3βconnected graph on __n__ vertices which can be embedded in the orientable surface of genus __g__ with faceβwidth at least __f__(__g__), then __G__ contains a
