EXAMPLE
|
A twin pack of primes contains 2 or more pairs of twin primes, between which pairs there are no other primes. 137,139,149,151 are in the sequence because they are consecutive primes which belong to more than 1 twin pair. 29,31 are not because both the preceding prime 23 and the next prime 37 are non-twins.
