## Definition of tween primes or what are tween primes?

For a pair of primes to be Twins, they must obey the following rule.

If i and j are twin primes, then both i and j must be individually primes and also should differ by 2, i.e. (i−j) = 2 or (j−i) = 2

Examples of tween primes sets (pairs):

(3,5); (5,7); (11,13); (17,19); (29,31); (41,43); (59,61); (71,73);
