It has been trial-factored up to 68 bits. I'm going to take it up to 69 in the next days.

That's a key step towards "Level 3" - 3 numbers trial factored to 2^69. Only one more to go! My P-Pro will reach it in about a week, but some of you seem to be using real computers and might get there sooner.

For example. Is it your desire to keep both numbers active on your computers, or do you want to release '319 from Active Status for you?

The beginning of this thread says it clearly. It's also on the Billions page at http://ElevenSmooth.com/Billion.html . Operation Billion Digits is a project to find a Billion Digit Mersenne Prime. It's also a joke, because finding a Billion Digit Mersenne Prime is far beyond the reach of today's computers and algorithms. There is a an estimate early in this thread that it would take over 850 years for each LLR test.

In the spirit of John Belushi from the movie Animal House, it's time for someone to make a futile gesture, and we're just the people to do it. The first step of a prime search is to trial factor candidates to remove those easily shown as prime (all the prime search projects - GIMPS, 17orBust, RieselSieve, 15k, 321, etc start with this). Prime95 couldn't handle billion digit numbers, so Luigi created a program that can.

Don't understand? Think of this as Spring Silliness in the distributed computing prime search community. It's better than swallowing goldfish. And even though it's essentially pointless today, Will Edgington's archive of Mersenne Factors means that when the day comes that somebody actually has a use for these factors, the factors we find will be available.

I am stopping here on this expo. I may grab some lower level ones and run them up a bit.

Oooops, looks I am getting *really* ahead of the game, I should have tested

3321928319 instead I tested
33219283319

bit of a difference!

When I get 3321928373 to 69 bits I'll go back and do the one I ought to have done in the first place!
