A bitwin chain of length one consists of two pairs of twin
primes with the property that they are related by being of the form:
|
(1)
|
The first few values of
generating bitwin chains are 6, 30, 660, 810, 2130, 2550, 3330, ... (OEIS A066388).
In general a chain of length consists of pairs of twin primes,

Bitwin chains can also be viewed as consisting of two related Cunningham
chains of the first and second kinds,

P. Jobling (1999) found the largest known chain of length six,
