Talking Predict M52

With M51 found and verified and only the official announcement awaiting, let's guess M52 (specifically, the next, currently unknown, Mersenne Prime yet to be noticed by a human.)

  1. Post your guess here, no PM'ing.
  2. Your guess must include a prime number (we are guessing the exponent) and/or date of discovery. No ranges, they may be ignored (or we may take the worst case of the range as the choice.) Failure to guess a prime number will count against you and impose a wait as in rule 6.
  3. You can not guess a number (or date) that has already been guessed. If you do guess a number or date that has already been submitted, this will count against you and impose a wait as in rule 6.
  4. If you guess a number that has known factor, at the time you posted, your guess will be ignored. It can have a 'composite' LL or PRP status (pending a recheck), but not a factor. Guessing a number with a known factor will count against you and impose a wait as in rule 6.
  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 3 guesses (for each number and date). If all exponents up to your number have had a first time test (or DC), you may select another, after a 60 day wait. Same (60 day wait) for date predictions that have passed.
  7. All guesses received within the 48 hours before M52 is reported (by or to anyone by any method) are hereby disqualified (to prevent cheating). This disqualification period will extend through to the time that a person reports to the forum that a candidate prime has been noticed. When that happens all guessing is closed.
  8. The discoverer of M52 (not the 'noticer') will have all guesses posted more than 10 hours after they were assigned and/or started the expo (whichever is first) 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. For the sake of this game, we will use the date (in UTC) that the prime is reported to and recorded by the PrimeNet server as the date (PRP or LL result). This may differ from the officially reported discovery date. If M52 is not first reported to PrimeNet, the judgement of the date to be used will be left up to George or his designee.
  11. Previous discoverers (not the noticers) of M Primes are granted an extra guess (4 vs. the standard 3). This means the person who used the machine that first reported the prime.

All previous guesses from other threads must be specifically restated.
Absurd guesses may be ignore it any statistical reports or graphs.
Rules may be clarified later. New rules for the next game may be suggested in this thread.
Make your guess clear in your post.
