- I am also confinced that such a chain is possible. It

will be extremely rare though.

You might want to check out:

http://www.ltkz.demon.co.uk/ktuplets.htm

A site which records record k-tuplet primes which is

not unlike your search for consecutive twins.

For example:

2845372542509911868266807 + 0, 4, 10, 12, 16, 22, 24,

30, 36, 40, 42, 46, 52, 54, 60, 64, 66, 70 (25 digits,

2000, Joerg Waldvogel & Peter Leikauf)

is the record 18-tuplet.

You haven't made it easy for yourself with 9

consecutive twins though;-)

Have you found lesser chains already? Say 3 or 4

consecutive twins?

There are 7 chains of 8 consecutive twins below 10^13, found

I guess that Jim Morton read this message and then asked our

PrimeNumbers list about this problem (9 consecutive twins).
