One of my guesses had the predicted date of 8/8/2020. Since we are more than 60 days past that date, I would like to make a new prediction:
149929849 on September 2, 2024.

I don't know whether my PC is fast enough to test this exponent. I can try 103347613 first. I just want to test every unfactored exponent between 103347000 to 103348000 and 103374000 to 103375000 It's extremely unlikely there are more Mersenne primes less than 100,000,000 as all of the prime exponents have already been tested at least once by someone.

This is the first Predict Mn thread on this forum for which the number of guesses has exceeded n.
I count 55 guesses (independently of whether they fit the rules at the time guessed). Last fiddled with by kriesel on 20201014 at 13:30 Reason: clarified meaning by adding "on this forum"

May be so, but my observation is still correct. Since there is no Predict M7 thread on this forum, the number of M7 guesses on this forum is zero. The discovery of M7 "somewhat predates" the Mersennes forum. Letters physically carried about Europe do not constitute an online forum thread. (How fortunate we are to have rapid communication by internet! Thank you DARPA.) https://www.mersenne.org/primes/
