For every finite m and n there is a finite set {G 1 , . . . , G l } of countable (m β’ K n )-free graphs such that every countable (m β’ K n )-free graph occurs as an induced subgraph of one of the graphs G i .

β¦ Synopsis
The cyclicity of a graph is the largest integer n for which the graph is contractible to the cycle on n vertices. By analyzing the cycle space of a graph, we establish upper and lower bounds on cyclicity. These bounds facilitate the computation of cyclicity for several classes of graphs, including chordal graphs, complete n-partite graphs, n-cubes, products of trees and cycles, and planar graphs.

In our efforts to study the niche graph of a tournament T , we have found it easier to study the complement, which we call the ''mixed pair'' graph of T and denote MP (T ). We show that an undirected graph G is MP (T ), for some tournament T , if and only if G is one of the following: a cycle of odd
It is shown that for every positive integer h, and for every > 0, there are graphs H = (V H , E H ) with at least h vertices and with density at least 0.5with the following property: any graph with minimum degree at least |V G | 2 (1 + o(1)) and |E H | divides |E G |, then G has an H-decomposition.
Let G be a graph and n β₯ 2 an integer. We prove that the following are equivalent: (i) there is a partition , and (ii) for every subset S of V (G), G \ S has at most n|S| components with the property that each of their blocks is an odd order complete graph.
