[QUOTE=nucleon;328168]On the exponent report, it now reports prime. But is there a report to see who did the TF/P-1 tests prior to the LL? I'm curious as my PCs did a lot of TF around that number.

Congrats to Curtis Cooper on his third huge Mersenne prime!

But the prime reporting procedure is not complete without a new button (pin)! :smile:

Such a report might be able to be provided by George.

I'd suggest everyone wait a few days for the surge to subside, and let George and Scott (and poor little Primenet) catch their breath.

The comments on CNN are hilarious: they are talking about prime rib, prime time, and prime posteriors. LOL

As for communication with with the press, I read once that when dealing with numbers it's best to give examples of their relevance, i.e. weight of 2x African elephants etc...

The thing is, the numbers we look at are larger than any physical quantity. By my rough calculations (and memory), in plank units the estimated known universe has a diameter of around 70+ digits, giving a volume of around 200+ digits. (Anyone is welcome to check these).

So there's nothing physical we can equate too.

But, I read we have 16 million (approx) base pairs in our DNA, which represented by G,T,A,C (4 states). By extension, that gives roughly, 2^32million, which is about the closest I can get for something physical. So I wonder if we can word something like, the numbers worked on are so large it's more than the combination of possible DNA sequences.

Or something a little closer that people can relate to, the numbers are so large it's like guessing not just the winning lotto numbers drawn, but correctly guessing the numbers played by everyone who bought a ticket.

Nada luck on mersenne.ca; not even ONE TF/P1 attempts. No record that such a number even exits. :surprised

Using only information that GPU72 owns, I can tell you that you didn't do any work on that exponent, but you did clear (read: found factors for) 432 candidates below before it was assigned to Curtis.

really I had to ask google:

2000 quadrillion light years in planck lengths

and got back just over 10^69 so is the diameter is 2 pentillion light years ?

Human genome has [URL="http://en.wikipedia.org/wiki/Human_genome"]over 3 billion base pairs[/URL], thus theoretical #possible sequences lies somewhere between the number of binary strings of the length of the 32nd and 33rd Fermat number.

I would be interested in seeing such numbers expressed in terms of "number of distinct legal n-move chess games". (In the sense of "through n moves", not "game over after nth move".) But due to combinatorial explosion, the resulting value of n would be far lower than the kinds of frickin-hugeness measures preferred by the press and the layperson.

I tried to submit the MLucas result into "manual results" on the server, and got nothing! :rant:

What did you expect - flashing lights, ringing bells and a rain of shiny coins? [I admit that would be pretty cool - maybe we should suggest adding it to the PrimeNet v6 to-do list]

Or perhaps some fish food for yourself and your dyslexic friend Fish2?
