In 1988, 268 of the world's brightest young mathematicians gathered in Canberra, Australia. Only 11 contestants fully solved Problem 6.
Among those who struggled was 13-year-old Terence Tao, who earned just 1 out of 7 marks on the problem, despite winning an IMO gold medal.
According to Arthur Engel's Problem-Solving Strategies, the Australian problem committee could not solve the proposed question, even though its six members included renowned mathematicians George and Esther Szekeres.
Four leading Australian number theorists were then given six hours to work on it. They, too, failed to solve it within that time. The problem was nevertheless selected for the competition.
At the IMO, Bulgarian contestant Emanouil Atanassov solved it and received a special prize for his solution. The official competition results confirm his full 7/7 score and the special award.
