Has anyone pointed out on this list yet that not only is 1999 a prime, but
also 1997 was a prime, so that we are going into the second part of a twin
prime number of years.
For the next pair, we'll have to wait 'til 2027-2029.
Do you think that the programmers, in their zeal to fix the year 2k
problem, have neglected to solve the year 10k problem? In any case, the
first twin pair after 10000 is 10007-10009.
Best wishes,
Sam Kutler
