What I do.....

Calculate first number, store in array. Calculate second number, check against first.
Recalc until different. Calculate third check against first and second - recalc until
different. Calculate fourth check against first, second and third - recalc until
different. 

The best way to iterate over the list is to stuff the good results into an array and
foreach over them.

Brute force? Yes. But effective.
