Default 2 big P1 factors found recently by the same CPU

Code:
Speck 41033441 F-PM1 2020-08-31 06:41 Factor: 12701256943476787953365441980792492997353 / (P-1, B1=1000000, B2=20000000, E=12) === 133.222 bits

Speck 41029441 F-PM1 2020-08-24 10:42 Factor: 145135143123598692565245877677438002712525001 / (P-1, B1=1000000, B2=20000000, E=12) === 146.702 bits

That's an impressive Speck!
M41029441 has a 146.702 bit factor: 145135143123598692565245877677438002712525001
M41033441 has a 133.222 bit factor: 12701256943476787953365441980792492997353

I guess we just need to look at exponents in the form 410xx441 to find big P-1 factors? :)

I am still continuing to beat you all with.... composite factors, haha.
But I won't be picky about the double amount of credit

M107930453 has a 77.779 bit factor : 259365338128498517663353 (note: found with P-1 with Colab)
The k is very low. it would have been found with a B1 @ 35111

That brings it to 199 digits of known factors out of 628 digits. A known forumite is doing the PRP-CF.

PrimeNet assigns it out anyway. The PRP will get done and a cert will get run soon.

And PrimeNet user "atrench" was impatient and did a PRP run that looks to be lacking in a VDF. So it will still need to be re-run.
