Interesting Facts About IMO

The 50th International Mathematical Olympiad is less than 1 month away. Here are some interesting facts about the IMO:

a) The first IMO was held in Romania in 1959.
b) Since 1959 the IMO has been held every year except 1980 - it was cancelled due to internal strife in Mongolia (will this year's IMO be cancelled due to H1N1?)
c) Singapore first took part in IMO in 1988.
d) China is the only nation that won IMO all-member-gold for multiple times (8 times).
e) Terence Tao (Australia) won a gold medal at the age of thirteen in IMO 1988, becoming the youngest person to receive a gold medal.
f) Singapore won her only gold medal in IMO 1996. It was won by Thevendran Senkodan from RJC.
g) Christian Reiher (Germany) is the current top contestant in the IMO Hall of Fame, winning 4 gold medals and 1 bronze medal. Reid Barton (USA) is second, with 4 gold medals.
h) The only country to have its entire team score perfectly (score: 42/42) on the IMO was the United States, which accomplished this remarkable feat in IMO 1994.
i) The easiest IMO must be the IMO 1987, as participants must score a perfect 42 to win a gold medal. Someone who scored 41 was ranked 23rd in that IMO.
