The first competition was held in 1985. It was not held in 1986. There are six problems a year, giving 108 problems to date.

Solutions are missing for 91/A2, 91/A3, 92 (except A1,A3), 94/B3, 95/A3, 95/B2, 01/A3, 01/B2, 01/B3. A better solution to 00/B3 would also be welcome.

Many thanks to Pablo César Torres who first suggested putting up these problems and gave me much help in doing so. Thank you also to those who supplied corrections to the questions.
