Fourteen countries participated. The British team of 8 boys, chosen on the results of the British Mathematical Olympiad held last May—D. J. Aldous, P. M. Bennett, A. J. Mclsaac, S. P. Norton, J. F. Segal, P. D. Smith, A. G. Trangmar, and N. S. Wedd—was placed fifth (after Hungary, E. Germany, U.S.S.R. and Romania). Mr. L. Beeson and I accompanied the team on behalf of the Association (which was asked by the Department of Education and Science to arrange British participation—and has also recently accepted responsibility for the mathematical oversight of the National Mathematical Contest and the British Mathematical Olympiad, presently administered by Guinness Awards on behalf of the organising committee).
