Some factors found so far. Each line is (b, n, sign, factor) i.e. the factor divides b^n-1.

Wow! Pascal is on the ball. From what I can tell these numbers have already been removed from the file.

There is probably more low hanging fruit currently due to that big RB being cleared.

I'm still chopping at the low-hanging fruit, using B1=11e7. I probably won't continue much past this week, though.

My local file now has ~1800 unfactored exponents.

Considering a week ago the file contained just under 2000 numbers, that's quite a feat.

Thank you Ryan !
You factored more than one in ten most wanted composites.
Now I can try to get to 10^2200.

Great!

Is it worth doing more ECM on the current mwrb2100, or are you going to generate a whole new file?

The numbers in this file won't disappear. New ones will be added.

Still plugging away with spare cycles. My local file has <1700 inputs now.

Let us know if there is an updated MWRB2100.. or would it be MWRB2200 now?

There is already a file t2200 of first-encountered composites replacing t2100.
There will be a last update of mwrb2100 in a week or two, only to see the impact of your nearly 300 factors.
There will be a file mwrb2200 in 2 or 3 months if nothing goes wrong, which will imply OPN > \(10^{2200}\).

What is the "most important" thing to contribute to now? t2200 or mwrb2100?
