Happy New Year! On the prime list I have changed how credit is listed in the proof-codes. Instead of usernames I am using surnames. This should be clearer...
I just set up a website listing more than 300,000 factors of n!+/-1. Thanks to Sean A. Irvine for the data. If anybody has more factors, please let me know!...
... Thanks to Sean, who sent me a list of factors, I set up a website where I put those data. There is still much work to do there, but you can already have a...
Hi Phil, I have all your old results from several years ago. I sieved both sides for n<100K up to 2*10^10. I kept all the factors found since I am more ...

David, Thank you. The CHG proof in 41 steps took the total of 676 hours with a single step (h=16) taking 228 hours! At least another 100 hours were spent on...
I suspected that some /heavy/ factoring had been done, but Predrag's details are awesome. I guess here is as good a place as any to remark on how amazing the...

A sequence of m primes in arithmetic progression is:- {p+a*k: p prime, a fixed, k=0..m-1} Clearly, a must be even. For the smallest value of a, namely a=2, the...
