    Default Giuga numbers!

    Is it possible to write a script that would print out Giuga numbers?

    List of current Giuge numbers^^

    Would be really cool to find an odd number that is a Giuga number!

    lol, this is a problem to be solved by proof other than brute force, enjoy crunching numbers for 20+years on a cluster

    You will most likely not find implementations in other languages.. Speed is the largest factor in such a program.

    Speed is greatly reduced for large numbers due to the usage of "BigInteger" arithmetic.. hence why only a few giuga numbers are known. The smallest odd Gigua consists of at least 9 primes. Good luck finding that with a "script".
