 2017-06-28, 18:24 #101 rogue     "Mark" Apr 2003 Between here and the 19C116 Posts Yes, I could update that, but I also recommend that participates search in ranges of 10000. As of now I will make that a requirement. As soon as you complete that base to 10000, I will do the update. Incremental updates waste too much of my time.

Also, your page has errors: You missed the prime (44^1288-1)^2-2 for base 44, and the prime for base 44 n=12909 is (44^12909-1)^2-2, not (44^12909+1)^2-2.

Thanks for pointing that out. I'll fix that as soon as I can.

Thanks for the corrections. Can you tell me if these were my mistakes? If it was my mistake, then it could be a typo.

The first mistake, (10^123+1)^2-2, should be (10^123-1)^2-2 (see Batalov's post, http://www.mersenneforum.org/showpos...40&postcount=7).
The second mistake, (114^3-1)^2-2, was originally found by lalera (http://www.mersenneforum.org/showpos...3&postcount=32). It appears as though you forgot to put it in the list.
Also, the prime (218^397-1)^2-2 is not on the list.

 2017-09-15, 18:09 #110 rogue     "Mark" Apr 2003 Between here and the 19C116 Posts Okay. I've updated my web page. If you discover another problem, please let me know.
