Sadly not everyone follows this forum.
I also had a squatter on the 1.1M I reserved.

That said Harlee did officially request 8.0 and 8.6 here so maybe he'll respond.

I look at the last 30 days activity in a range before I start it and then if someone jumps in hard where I am I may move on.

Now all these ranges have 4000 exponents with known prime factors. So I unreserve them.

Interesting goal; moving on to 17.x next?

I want to reserve 17.6M, 17.7M and 17.8M.

The range 17.1M requires extra TF that I cannot perform because I do not have a powerful GPU.

I'm not sure. It's already 50-50 at 74/75 bits.
Might get 10 factors to finish it to 75 bits.

This range might just need more aggressive P1.

And while you were having this great success, over 3 days, I had 73 no factor found P-1 results in a row.

Now I feel bad.

For the record my record for this project is 115 without a factor.

TF Tidy-Up below 50M (getting all exponents above "x" bits): All exponents above 38.1M at 73+bits All exponents above 36.8M at 72+bits Last fiddled with by petrw1 on 2022-07-05 at 02:55
 2022-07-06, 14:35 #154 linament   Nov 2013 25 Posts Recently, I mentioned that user harlee had reserved many exponents in my range, 8.8M. A few days later these were all released. Now a another user, Cong Shengzhuo, has reserved many of the exponents in the 8.8M range. This is becoming annoying. Last fiddled with by linament on 2022-07-06 at 14:39
