[QUOTE=Thecmaster;514227]Where and how can you check bitlevel on a factor?[/QUOTE]Once the factor shows up on mersenne.ca (data sync happens nightly around 2am UTC) those details are available for each factor.

Oooh. Didn't know about that.

I found a factor a week ago: 73683712459653894665954956209427783 and that are 115.827 bits.

My largest factor so far. ;)

Thanx for info

So then looking at [url]https://www.mersenne.ca/M90883987[/url] you can see the bitsize of the factor, as well as a graph showing how the factor fits into B1/B2 of the P-1, how it compares to TF that was done, etc.

edit: your factor is #485 on the list of largest P-1 factors ever found (out of 89,828).

Oooh. Is that so. I been doing this for a month and have been lucky so far. I found a factor my first day of TF. TF number 8 for me got a factor. But p-1 haven't yeald resault for me before this 115.827 bit factor. After 3 weeks of p-1 and after 4 weeks I now got an other factor.

Thanx for the stars if the factor.

Cheers and happy easter

Where did you find that list? 😁

I completed ECM for 360000-40000 range with 30-digits bounds.
36 new factors were found(one of them is 41 digits).

400000-440000 range is next.

[QUOTE=Thecmaster;514275]Where did you find that list? 😁[/QUOTE]Fiddling in my data. I've exposed a quick report that may be of general interest:

Yeah. That's nice. And fun to check out. There are soon big factors in the top 100 factors. 😅

Ryan Propper has become the low-level Mersenne number killer.
He found the next factor, this time for M4111 - 10819968927585403636958816179849566933560096066787125831.
RPR is prime.
Congratulations!

To find as many factors as he has should take Thousands of curves yet if you look at ECM top producers he is about 750th with .004 points and 8 factors in 8 attempts. Either he doesn't report curves run for unsuccessful attempts....or these aren't actually from ECM? OR????

A couple years ago I ran 1,000+ curves on each unfactored exponent under 20,000 for about 19,000 GhzDays. I found 2 factors under 9999.

Wouldn't the rest of us want to know how many curves are completed at each level so we know where best to continue to finish factoring them?

[QUOTE=petrw1;515241]Either he doesn't report curves run for unsuccessful attempts....[/QUOTE]

This is the simplest explanation

EDIT:- It is unlikely that he's using GIMPS/P95 to get assignments/report results. Most likely these are being run using GMP-ECM.
