Thank you gangho. Remember to reserve your next exponent in the "checkout thread", so that no one else will reserve it while you work on it.

Hi Luigi,

nice factor, the 2nd largest OBD factor so far?! :smile:
For GIMPS it doesn't matter how big a factor is, a factor is a factors and thus the mersenne number can't be prime. But bigger factors are more impressive than smaller ones because (usually) they are harder to find.
