M103830131 has a 157.127-bit (48-digit) composite (P24+P24) factor: 199531333730879095999006796725214407904194653871 (P-1,B1=1708000)

While the composite factor itself it not extremely interesting by itself, I find it interesting because:
- it was found in stage 1.
- the prime factors are very similar in size (78.460 and 78.667 bits).

The prime factors are 415767534785818078323247 and 479910808412848576977793.

M106722533 has an 110 bits factor 771972811871697820846912678000249.

Albeit 110 bits is not a joke, the factor is not a record in itself, but it is quite large and nice, considering the fact that was found in stage 1 (yes, it is sooo smooth, like ice cream!)

Liar! Only 109 bits, 109.25 to be more exact.

Why stop there? 109.25024907447

But LaurV isn't wrong, the factor does take 110 bits to represent. You don't say it's 32.8876 decimal digits long.

Oops.

From my "I can't count" liturgy:

Versicle: How many bits in two to the first power?

Responsory: Two, two.

Versicle: How many decimal digits in ten to the first power?

Responsory: Two, two.

From the output of Pari-GP:
Code:
? v=binary(771972811871697820846912678000249)
%1 = [1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 1, 1, 1, 0, 1, 1, 0, 0, 1, 0, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 1, 0, 1, 0, 0, 0, 1, 0, 1, 1, 1, 1, 0, 1, 0, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 0, 0, 1, 0, 0, 1, 1, 1, 1, 1, 0, 1, 1, 0, 0, 1, 1, 1, 1, 0, 0, 1]
? #v
%2 = 110
?

A nice run of the mill 79 bit factor: 1025757166134493292294953
But, it was found when I poached (not sorry) a stalled P-1 that was in the lowest 25 exponents for FTC.
103547179
There are others down there that have zero check ins since assigned and are more than a month old and thus have violated the rules for Cat 0 (but the rules do seem to apply to P-1 assignments down in the low FTC's)
  • Must be completed in 30 days
  • Assignments are recycled if assignment is not started with 7 days or when assignment is more than 30 days old.

Just so you know, I'm working on those held by ANONYMOUS and Kas. Should all be done in about three days (assuming Colab cooperates).

I have been working bottom up getting about 9 every 5 days.

Yeah. I am aware you are on a certain team...

Just wanted to declare intentions, so we didn't duplicate efforts. A Compute Cycle is a terrible thing to waste!

Oh, didn't realize that. Sorry, LaurV.
