Problems from the Eighteenth British Combinatorial Conference
Peter J. Cameron · 2001
Most of these problems were presented at the problem session of the 18th British Combinatorial Conference at the University of Sussex, 2‐6 July 2001. I have added some problems given to me after the session. Since two of the problems concern circular chromatic number, the entire set has a circular structure; the starting point is fixed by the sixth problem.
