With p,q,r consecutive prime integers, we may try to extend the problem. For example, what are the solutions of: abs(p*q*r - n^3) < 20 Are 2* 3* 5 - 3^3 = 3 and 7*11*13 - 10^3 = 1 the only solutions??? Instead of using 20 or any other integer, same question with: abs(p*q*r - n^3) < r Or some other maximum? Christian.
