Many thanks to all those who supplied solutions where I failed, or pointed out
errors, or supplied better solutions. There are still some solutions which are
clumsy or inelegant, and maybe even some which are wrong (although I am not
aware of any). All suggestions for improvement would be most welcome. It would
also be good to supply hints which just gave the key idea. Any contributions
welcome. [email: jscholes@kalva.demon.co.uk]
Thru 2001 there were 42 IMOs, each with 6 problems, except for 1962 which had 7,
giving a total 253 problems in all. I have numbered them randomly from 1 to 253.
