## Abstract G. Ringel conjectured that for every positive integer __n__ other than 2, 4, 5, 8, 9, and 16, there exists a nonseparable graph with __n__ cycles. It is proved here that the conjecture is true even with the restriction to planar and hamiltonian graphs.

In this paper, we will prove that every graph \(G\) with minimum degree \(\delta(G) \geqslant 3\) contains a cycle of length divisible by three. This was conjectured to be true by Barefoot, Clark, Douthett, and Entringer. 11994 Academic Press, Inc.
This paper determines lower bounds on the number of different cycle lengths in a graph of given minimum degree k and girth g. The most general result gives a lower bound of ck ~.
Let S be a finite set and u a permutation on S. The permutation u\* on the set of 2-subsets of S is naturally induced by u. Suppose G is a graph and V(G), β¬(G) are the vertex set, the edge set, respectively. Let V(G) = S. If β¬(G) and u\*(β¬(G)), the image of β¬(G) by u\*, have no common element, then
## Abstract Let __p__ and __C__~4~ (__G__) be the number of vertices and the number of 4βcycles of a maximal planar graph __G__, respectively. Hakimi and Schmeichel characterized those graphs __G__ for which __C__~4~ (__G__) = 1/2(__p__^2^ + 3__p__ β 22). This characterization is correct if __p__ β₯
