Trial factoring to 2^76 on M332,192,831 is now 50% complete. Still no factor found. I will post updates on my website by this evening.

Trial factoring to 2^76 on M332,192,831 is now complete. Still no factor found. I am now trial factoring to 2^77, which will take approximately 7 weeks. If no factor is found, I will begin P-1 testing, which will take approximately 2 months. If still no factor is found, I will begin the LL test!!!

Default Team StarQwest Updates

Team StarQwest has now surpassed 200 CPU years of LL testing!!! The team has successfully tested 20 mersenne numbers, all of which have turned up composite. Trial factoring on M332,192,831 is now 20% complete to 2^77 (54.3% complete overall). This will finish by the end of April, and if no factor is found, I will begin P-1 factoring. I have posted all the updated information on www.StarQwest.org, as well as some other cool stuff, so be sure to check out the entire site. My StarQwest site contains all the info for the team and prime number testing, as well as other neat stuff, such as spacecraft designs and a musical score I composed. You can also download one BILLION digits of pi (3.1415926535...) if you so please, which took me over 17 hours of computer time to calculate! I have also fixed all mistakes and dead links that I found, so there shouldn't be any errors.

Default M332,192,831 update

Trial Factoring on M332,192,831 is now 50% complete to 2^77 (71.4% complete overall). It will be finished in approximately 25 days and will be worth approximately 20 CPU years for factoring! Wow, 3 months of trial factoring for a single exponent! I could have LL tested 3 ten million digit numbers in this time. P-1 factoring will likely take about 2 months. Even if no factor is found, this will put Team StarQwest around rank 350 for factoring!!! I would like Team StarQwest to be in the top 100 for factoring eventually and find lots of factors, so anyone interested in factoring work is more than welcome to join the team. Finally, if no factor of M332,192,831 is found and I begin the LL test, it will still be open for double check. Anyone (member or not) is more than welcome to double check this number.

Default 100,000,007 doublechecked!

Comparing the residue posted at your website with the one listed in cleared.txt report, there is a LARGE chance that your exponent has been sucessfully DCed.
Congrats to you and yxine!

I have had some technical difficulties with my website, so I couldn't post anything. However, I did finish trial factoring M332,192,831 to 2^77 and no factor was found. It is now P-1 factoring, which will take a lot longer than I thought, which is unfortunate. It will take another two months to finish stage 1 and I don't know how long to finish stage 2. I will post updates on the website when I get it working again.

I barely have the patience to stay on a project for a month, if you manage to be the first one to complete a 100-million digit Mersenne number test, I will be EXTREMELY impressed with your patience.

Here is the StarQwest Mission Statement, from www.StarQwest.org:

"The name of StarQwest is a symbol for pride and achievement, for glory and desire, for learning and truth. StarQwest and anything bearing its name will strive for greatness, test the boundaries, and go where no one has gone before. It is an honor and a responsibility, a vision and a dream. To set sail for the stars, and begin the quest of a lifetime, searching for greater understanding and majestic scientific endeavors, and for an amazing journey unlike anything ever seen. StarQwest reaches for the stars and beyond, to learn, to inspire, and to explore."

I am currently laying the groundwork for this test, which will be the largest ever performed, by doing early factoring work. Considering into my calculations that over time I will be upgrading to faster computers, I can see this test finishing in around 4 or 5 years time. This is one of my pet projects. I was the first to test a number larger than 100M. That number was 2^100,000,007-1, which contains over 30.1 million digits. Yxine became the first to successfully doublecheck that number just a couple of days ago. Both of our tests (mine and Yxine's) have now proven conclusively that M100,000,007 is not a prime number. This is the first time that anything definate can be said about the primality of a number of this size. I don't know who will be willing to doublecheck M332,192,831, although I'm sure that someone will be brave enough to take up the task for themselves. It will be worth about 900 CPU years- the equivalent of ~120 ten million digit tests!

Default M332,192,831

I have resolved all the technical difficulties with my website and uploaded all the data about M332,192,831! P-1 stage 1 factoring is now 6.57% complete and will finish in about 10 weeks. Stage 2 will likely take 3-4 months. Ugh. There will likely be a cold day in hell before I know the primality status of this number.

Hehe, just for fun I make a definite statement about the primality of a really really big number.

MMMMMMMM4 is not prime! And indeed no matter how many more M's you might like to add you will never ever get a prime number.

okay, I know, you probably meant a number with a prime exponent, right?

I'll go back to my corner now. Thanks for reading.
