USA Mathematical Olympiad

The Mathematical Association of America (MAA) has announced the twelve winners of its prestigious 2008 USA Mathematical Olympiad (USAMO).

More than 225,000 high school students competed in a series of challenging contests put together by the Mathematical Association of America's Mathematics Competitions program, which culminated with the challenging USAMO exam.

On June 7-8, the winners will take the rigorous team selection test to try to qualify for the U.S. team, which will compete in the International Mathematical Olympiad (IMO), to be held in Madrid, Spain, July 10-22. That team will consist of the six students with the highest combined scores.

Magic Cube Generator

Dwane H. Campbell and Keith A. Campbell focus primarily on a set of 8 by 8 by 8 magic cubes that are often called perfect magic cubes of order 8, Nasik magic cubes of order 8, or order-8 pan-2,3-agonal magic cubes.

There are 3,295,497,267,707,904,000 (almost 3.3 quintillion) visually different magic cubes described in this set. All cubes in the set have over 10,000 different ways to sum to the magic constant.
