- I have just discovered the first known 27-digit prime 18-tuplet:

159272023128204753638724847 + d,

d = 0, 4, 10, 12, 16, 22, 24, 30, 36, 40, 42, 46, 52, 54, 60, 64, 66, 70

(27 digits, Jan 15, 2010, Jaroslaw Wroblewski)

This is the largest known 18-tuplet and the largest known case of 18

Simultaneous Primes.
