Under 20,500,000
Less than 500,000 to go until the entire range (to 999,999,993) is under 20M factors.
https://www.mersenne.ca/status/tf/0/0/1/0 I know this shows 3 to go but there have been more than 3 factors found since this report was produced. 1 year ago it was: 20,872,807 2 years ago it was: 21,198,206

I guess as the "inventor" of this project...

There are actually 21 ranges that Oliver has completed to 74 bits (22.8 is special ... he is finished). P.S. within a few weeks he will probably complete the rest (fingers crossed) I have ordered them by "ToGo". Then I have suggested P1 effort. Always work on the exponents with B1=B2 first. Do not fear that some ranges have NO B1=B2 remaining. Most of these exponents have had very meagre P1 based on today's hardware. In these cases look for low B1/B2 here . Sort by B2 (click on the column) and start at the top. The top exponents will likely have a current P1 success rate of under 2%; most will be under 3% Choosing a B1/B2 that give 4% (+2%) for example will require on average 50 exponents per factor. Each assignment will take about 2 GhzDays ... not a whole lot, right? Code:
Range To Go B1=B2 Low P1 This first bunch have so few remaining; don't pick B1/B2 with over 34% success rate 22.8M 1 302 29.6M 1 579 122 25.1M 2 497 162 24.6M 3 189 22.1M 4 265 23.6M 7 602 258 27.4M 9 761 163 22.7M 10 130 322 26.3M 10 722 145 28.1M 17 679 161 27.3M 17 712 153 27.7M 23 770 159 28.2M 24 610 157 28.5M 24 330 153 28.9M 25 643 154 27.5M 26 382 175 For these we'll need about a 55.5% success rate 27.8M 41 791 179 29.0M 47 715 176 28.0M 50 531 163 These 78% but probably better another bit of TF and then something more reasonable 27.2M 89 821 150 29.8M 113 789 100

OK... I had actually mentioned 22.xM for a reason...
I'm personally working 29.6M, 24.6M, and 27.4M. The GPU72 Colab P1'ers are working 25.1M, and will then move to 23.6M. Last fiddled with by chalsall on 20210917 at 14:37 Reason: Dyslexic moment.

I'd like to take 22.1M 22.7M and 22.8M, I guess that shouldn't take long.

Trivia: Since I joined this search ~100 days ago, there were 10563 factors found, from which I found 563 and the "others" found exactly 10000. That is ten thousands factors, sharp! Which you, guys, found in 100 days sharp... (about, actually there are 102 days, but don't tell anybody!)
Which is a good opportunity to boast... For a while I was founding ~80% of the factors, till SRBase joined, and my percent decreased to ~30%, then Oliver started to report his "bucket" of factors, and I went to about 10%. Since I stopped (as mentioned in former posts), people continued to report factors, and I am now at the shown ~5% from the whole amount. When I joined, there were 214 "ranges" to go, currently there are only 181. From the 33 "killed" ranges, I have found 549 of the total 2530 factors, which puts me at ~21% of the "killed ranges' factors". I was at about 40% when I "left", as there were about 7 or 8 ranges closed since. Last fiddled with by LaurV on 20210923 at 09:49
