Sorry Jocelyn; no offence intended.

If you want to message her I think her id is: jocelynl1204

mikr had been systematically TF'ing all ranges down as low as 4M to 71 bits.
Only recently have I seen him doing P-1....his bounds are a little better.
I'm not sure how to message mikr
Thanks, when I picked the 3.8M range I did not see that someone was already working there. The pool of exponents is big and there is no reason for me to jump in to a range someone else has already been working. I will try to PM both, let them know of this thread and that I will be moving on to another range shortly.

Can you put me down for 4.0M, I will move there next week.

In the past couple decades, I have been mainly working on factored numbers in the range 3M. In recent months, I added the unfactored ones to my list. But since there is a common effort in the ranges below 30M for unfactored ones. I will leave the field open for you all in that range. There are plenty of factored ones to keep me happy for another decade; I hope!

Default My first attempt at a status update.

I officially started on this project April 16; however unofficially it was mid-January when I decided my next project would be this one and I started using the prescribed bounds to complete my last TWOK ranges.

Some of you started working here in March. So if no one objects I will arbitrarily choose March 1 as day 0.

Also, I don't know of any way to easily determine what method was used to find a factor (TF, ECM, P-1, P+1).
And I only know how to easily report newly factored exponents; not total factors found including extra factors for already-factored exponents.

I'd like to be able to include a count of exponents remaining to P-1 but I'm having trouble determining the "guidelines".
This is where mind is at (whenever it is not wandering off somewhere else):
1. I use mersenne.ca to list for every exponent of interest (under 20? 30? 40M?)
--a. Current bounds and TF level
--b. Proposed new bounds
2. Then I need to determine the current and proposed P-1 success percent.
--a. I have the source for prob.php but I'd prefer a much simpler approximation that I could make into a formula.
--b. I'd be content if it was even within 0.5% or less given my proposed target is in the 3% range.
--c. I'd like to believe it could be approximated with a "quadratic??" taking into account: Exponent, TF-Level, B1 and B2.
--d. It just occurred to me that with all the ECM done in the low ranges the calculated P-1 success percent will NOT be very accurate unless it is also taken into account.
3. Propose what success differential is worth pursuing and count those; maybe something around 3%???
--a. I observe that some of you are methodically P-1'ing every exponent if your ranges; I have no problem with this...it's your rig.

So until someone more knowledged enlightens me I will start with this to report total new factors with each update:
PS: The ToDo is arbitrarily Proposed/Current B1 * P/C B2 > 100 ... and I currently only have data up to 20M for this.

Code:

Range	Exps.	ToDo	Factors	Factored

@petrw1

I started on 03-22-2022 so you missed a few exponents in the 4.2M range

4.20M complete with 12 factors found
4.21M complete with 15 factors found
4.22M complete with 17 factors found
4.23M complete with 7 factors found
4.24M @ 37% with 7 factors found so far.
current total 58

Ok; I backed up so day 0 is March 1.

You didn't have to do that. This is your game you set the rules. I was just bragging.

I'll get to work on 8.2 - 8.3
Currently using an 10400f with about 4ghz, and 8 GB of ram.

Edit: Appears someones already hit those, will keep searching for an untaken assignment.
Second Edit: I'll just work on the ones that have been missed.
