Let $f(n)$ be the smallest number so that there are two $n$ chromatic graphs whose product has chromatic number $f(n)$. Under the assumption that a certain sharper result than one obtained by Duffus, Sands and Woodrow \cite{DSW}, and Welzl \cite{W}, holds we will prove that $f(n)\geq {n/2}$.

## Indivisible homogeneous directed graphs and a game for vertex partitions

Sauer, Norbert and El-Zahar

Let $\mathcal T$ be a set of finite tournaments. We will give a necessary and sufficient condition for the $\mathcal T$-free homogeneous directed graph $\Ha_{\mathcal T}$ to be {\sl divisible}; that is, that there is a partition of $\Ha_{\mathcal T}$ into two sets neither of which contains an isomorphic copy of $\Ha_{\mathcal T}$.

## On the relative distances of six points in a plane convex body

Langi, Zsolt and Böröczky, Károly

Let $C$ be a convex body in the Euclidean plane. By the relative distance of points $p$ and $q$ we mean the ratio of the Euclidean distance of $p$ and $q$ to the half of the Euclidean length of a longest chord of $C$ parallel to $pq$. In this note we find the least upper bound of the minimum pairwise relative distance of six points in a plane convex body.
