Subject: Re: Mersenne: hi everyone

 I cannot help wondering if this is the sequence M(2), M(M(2)), M(M(M(2))),
 etc, which is indeed prime for all terms even vaguely capable of testing
 at the present time.

 The problem is that 90 digits in the exponent seems high for M(M(127)),
 the next term in the sequence.

My understanding is, that in the absence of any number-theoretical reason to
believe this sequence always prime (or otherwise to believe M(M(127))
prime), it's generally expected to be composite.

Big, big disappointment here in Norway -- I was outside for
about an hour
during the maximum, _nothing_ to be seen. No clouds at all,
perfectly
clear, but not a single meteor. :-(

Let's hope the prime verification goes better ;-)

If - and of any worth - I would accept a database in almost any size at
my network if it could help factoring faster.
 
And anyway who am I to suggest this:

I have been wanting to do that number theory conference in Monterey.
Perhaps invite the number theorists to join us?

Alternate suggestion:  have a small gathering of the locals at the
Tied House in Mountain View some weekday evening the week
after Thanksgiving, and do still get together at the Monterey
math schmooze?  spike

  meets in Monterey (acutally Asilomar)

 then it would follow we should meet in the Monterey area.  Santa Cruz is a
 45 minute drive from Monterey, silicon valley 90 minutes or so.  I'd be glad
 to recommend a restaraunt for this, I've lived in the area since 1977..  One
 of my favorite places down there is a superb Chinese restaraunt in Carmel,
 but this would only be suitable for 8-12 people max.  There are lots of
 other good places down there, or if folks wanted to drive a *few* miles, we
 could meet in Moss Landing at Phil's Fish Market for the best chowder and
 choppino on the west coast (and all kinda other fresh local seafoods as well
 as some pasta dishs for those who won't eat fish).  Phil's is quite large,
 and if we have a headcount, reserving the back area on a tuesday shouldn't
 be too tough.  I think this would work for 20-30 folks there.

Re: Mersenne: Re: SF Bay GIMPS party (was Mersenne #39)

2001-11-19 Thread handmade

I am not interested in parties, ratings for highest contributions, number
assignments, or information on microprocesor speeds. 

I am writing a machine language program to find the next 'greater than
10,000,000 digits' mersenne prime.

Anyone have any ideas for a algorithm, or approach that has not been
discussed lately?

Thanks
Dan
