Largest PM1 factors?

Is there any page tracking world record largest factors found via PM1?

I thought I remembered seeing one somewhere, but maybe I was thinking of ECM.

Ah, thanks.

Somewhat interesting that none of the top10 are factors of Mersenne numbers.
Anyone keeping tabs on Mersenne specific records like that?

edit: I only just started doing some PM1 work, but my best so far is a measly 29digits.

Ah, yes, very nice. Looks like I've got a ways to go before making it into the record books :smile:
