Trippple Checks

[Madpoo]

Here's another update. A few more factors were found and ATH checked in a couple LL results. I've also hopefully added in notes for the different ranges people have elected to tackle.

Well, um... this is embarrassing but apparently I keep retesting this one number over and over. :)

Originally I picked it because I suspected the first check was bad, based on the history of that computer. Then I accidentally put that same exponent on two of my systems. Oh well, so I gave it a double-check.

Now I just realized I triple-checked it because it was included in the list of exponents that had been self-verified. Oops!

Here's the one in question:

I really have tested this on 3 different machines now but in the interest of overall integrity, if someone else wanted to they could do an independent check, but I felt like I had to explain the circumstances and how it happened.

I would like to lend a hand. I'll take the exponents in this list that are between 30000000 and 35000000 (for TF only).

Awesome, I've noted that.

There's a user "Nesowa" who has been doing some TF work on exponents in the 38M range. I don't think I saw any mention of it in this thread, so just be aware that someone is doing those.

I think it's a user that is doing extra TF in general, not just limited to the ones in the list here, and they just happen to be up to the 38M range at the moment.

I'm attaching an updated list with the latest removals (factors found, some LL results checked in) and updated factored-to levels. All of the exponents up to 20M have been factored to higher levels (up to 69). I don't know if that's how far "manfred4" was going to take them?

I don't think anyone has spoken for doing LL work on 17.5M - 20M so those would be some nice quick work for a good machine, if anyone is interested.

Nesowa is a "big gun", I watched him for months as we overtook each other in tops a number of times, his work is ok, he is finding the expected number of factors, in spite of the fact he doesn't talk too much here around. Hey buddy, you may say something, if you read this..

I'll take them. Not sure exactly how long it'll take, but I'll post when they're finished (and will submit them every so often).

That is how far I wanted to factor them. My other batch should be finished as well, but I can't look there because that PC is still disconnected from the internet.

I see that some others were factoring to higher levels, but I just got them to the point, where LL would cost less time to clear thatn TF now, but if anyone wants, they can factor those further.

I'm taking the ones I reserved to 71bits, but I didn't run a comparison with OpenCL-Lucas (or whatever it is called for AMD cards). I might do your range a bit further, but I'm first doing my own ranges and see how far the LLers progressed by then.

Whoops, for the very first I "wasted" two LL tests....

I currently have 5 cores continuing this work.....each will finish 1 exponent in about 2.5 - 3 days.
