Can you solve the following equation?
½ = 1/x² + 1/y² +...+ 1/z²
All variables must be different, positive integers, and there must be a finite number of terms.

"Then n * (1/a^2) > 1/2"
But you really meant
"Then n * (1/a^2) < 1/2"
And when you say what you meant, you find that your proof no longer works.
