Hi,

Congratulations on the find, is this part of a project, or are you working
on Repunits alone? Did you use any kind of sieve in the search? (I'm
certain one could be written that would be about as fast as the factorial
sieve, I'm guessing you couldn't go better than that though)

I assume there is no chance of a proof of primality, a shame really - even
if the Generalised Riemann Hypothesis was proved it would take a very long
time to run all those SPRP tests!

Are you going to continue searching for higher repunits? Maybe a search
could be organised (although it might be hard to get people to search for
non-archivable primes).

Sorry if that sounded like 20 questions, I was surprised by the lack of
response to this find (maybe everyone is in shock from Conrad Curry's
announcement that he'd found the remaining factors to prove (402^2521-1)/401
prime).

Michael.
