Default Predict M42

Ok, folks, moving beyond the poll, let us try to predict M42.


THE RULES OF THE GAME:
  1. Post your guess here, no PM'ing me.
  2. Your guess must be a prime number (we are guessing the exponent).
  3. The guesses are for 'M42', that is: the next reported Mersenne prime that is larger than the 41st known Mersenne Prime, namely 224,036,583-1
  4. You can not guess a number that has already been guessed.
  5. If there is a tie (i.e. 2 posts are equally close and meet all other rules), the first post gets it.
  6. You may post 1 guess every 90 days (after posting a guess you must wait 90 days, not wait til a new quarter).
  7. All guesses received within the 48 hours before M42 is reported are hereby disqualified (to prevent cheating).
    I ask the moderators to lock this thread when M42 is reported.
  8. The discoverer of M42 will have all guesses posted more than 4 days after they were assigned the expo that is reported to be prime, hereby disqualified.
  9. If the prime that is reported fails the rechecks, those disqualified in 7 and 8 will be restored.
  10. Commentary should be greatly restrained.
  11. Further rules may be added if needed.


From time to time, I may post stats on the guesses.

Is there any "Moore's" law that can be applied on primes?

I think he meant the largest known prime by year. If I didn't have a midterm exam tomorrow, I would look for that.
