Get one half by squaring (Posted on 2004-09-20) Difficulty: 4 of 5
Can you solve the following equation?

= 1/x + 1/y +...+ 1/z

All variables must be different, positive integers, and there must be a finite number of terms.

Come on, Charlie!  I did that much and more with just my TI-83:  see my first post, the next term is 19026245

I was hoping for a program that would somehow try permutations, like use the 2, 3, 4, 5 but leave out the 6 and them stop creating the sequence if it reaches 10000 and try a new few starting numbers.

I established that you need the 2, but maybe it would try starting with subsets of {3, 4, 5, 6, 7, 8, 9, 10} 

This wouldn't be guaranteed to find a solution, but it might.
