Lord Julius vs. TJAOI
 

I'm surprised that Lord Julius is finding so many TF1-61 factors when I was of the understanding that TJAOI systematically churned through every exponent and every bit level up to 67.

My bad. Never mind.
I thought only new factors were reported.

Yep, quirk of how the system is coded/defined, but not doing GIMPS stuff for stats or credits.
Been going after TF gaps sporadically before, but with the new TF gap list making it easy to feed mfaktc just started at 100,000 and headed up!

[QUOTE=petrw1;601366]I thought only new factors were reported.[/QUOTE]Yeah, the "recently cleared" report shows factor results even if they're not new. You can see on my [URL="https://www.mersenne.ca/recentfactors.php"]New Recent Factors[/URL] page that no factors <68 bits have been found this year.

M[M]109031903[/M] has a 168-bit composite factor: 363837089775240211801734278322914708564840813653583 (183216050087127739855367 78 bits * 1985836336948748649699241849 91 bits).

My first composite P-1 score. Interestingly, the full composite factor could have still have been found with just B2 = B1 = 75,000; the 91-bit component could even have been found with B2 = B1 = 20,000.

Speaking of composite factors, I found this beauty some days ago:

UID: lycorn/supernova, M13651679 has a factor: 3472625743771127990613030299559770254509858718433711042922231204290885145343 (P-1, B1=1350000, B2=3789310980)

[B]250.941[/B] bits. And:

Composite factor 3472625743771127990613030299559770254509858718433711042922231204290885145343 can be split into:
503052987459241976394793
1034412296803300959988489
6673452496002985441495464559

It´s the largest factor I´ve ever found , and the first time I find a composite factor that can be split in 3 factors

Strangely I noticed yesterday that [i]masser[/i] found this:[quote][M]M27893851[/M] has a 249.057-bit (75-digit) [b]composite[/b] (P23+P25+P28) factor: (P-1,B1=200000,B2=49465920)

It is not much, but it is something.

Nice. Huge one.
