Re: Mersenne: M38 = M6972593

NOW it does, after the official announcement   Remember
when Roland found M37?   Someone found a 0x000 
residue in the report and beat George to the punch, so Scott
modified the reports so that they would NOT post a zero 
residue automatically.   So THIS time, when word came that
we'd found a potential prime, some enterprising person
immediately grabbed the "assigned exponents" file, and the
"cleared exponents" file, and by the process of elimination,
deduced the prime number because it was the ONLY candidate
listed as "assigned" but was not EITHER cleared as non-prime
or still in progress.

Actually, it was updated and added on July 5.  Previously,
the cleared exponent list looked like the following
(accounts removed for space):

6972451 62 0x1921D245846367__25-Jun-99 15:07  
6972467 62 0x01123F0756E444__03-Jul-99 11:27  
6972509 62 0x681B51793464A4__17-May-99 06:07  
6972617 62 0xC377193C8903C1__05-Apr-99 05:25  
6972649 62 0x30982ED7214ACA__09-May-99 12:49  
6972709 62 0xEADF232189A0F0__21-Jun-99 08:30  

George was telling Scott to correct for this 'leak' so that
a really determined person could not do a comparison-elimination
to deduce a prime number find before George announces it.

Fixing this one 'leak' won't do the job, if you know how
and where to look...

Besides, *some people* know how to keep quiet about certain
things.  You didn't see this person going around announcing
it to the world immediately after it was found, did you???
In fact, their website didn't post it being found until after
it was verified, and even then, didn't disclose the number!!

On the other hand, they could've noticed a discrepany and
shrugged it off as meaningless until after word got out a
new prime was found.  At that point, they could've gone
back and said to themselves '*that explains the discrepany!*'.

Just a couple of possibilities

Of course, Curt Noll's web page made that a pointless exercise... ;-)

 (Note to Scott - create a dummy non-zero residue a stick it
 in the cleared exponents report).

I'm curious - had this already been tested by
someone else using the defective v17 software?

Mersenne: M38 = M6972593

1999-07-04 Thread George Woltman

Hi all,

As the newspaper should announce the new prime on Monday or Tuesday,
I've placed the info on the new prime at http://www.mersenne.org/prime.htm
Congratulations to Nayan Hajratwala and all GIMPS members for our fourth
success!

Each Mersenne announcement is different.  This time round I finally
figured out how to get the press interested in the new number - tell them
its a secret.  The Oregonian was doing an article on Richard Crandall and
when the found out there was a new prime and we wouldn't tell them what it
was, their interest level went way up!

I admire the resourcefulness of GIMPS members for going on a 
"scavenger hunt" and finding out the exponent a few days before this
email was sent out.  However the resourcefulness award must go to one
enterprising GIMPS member that dug through all the cleared and assigned
exponent lists and human-readable files and deduced the exponent in early
June!  (Note to Scott - create a dummy non-zero residue a stick it
in the cleared exponents report).

Good luck to all in the search for M39! 

Have fun,
George
