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!) Last fiddled with by LaurV on 2021-05-29 at 14:38 |

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)

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).
