In number theory, a bi-twin chain of length k + 1 is a sequence of natural numbers in which every number is prime. The numbers form a Cunningham chain of the first kind of length , while forms a Cunningham chain of the second kind. Each of the pairs is a pair of twin primes. Each of the primes for is a Sophie Germain prime and each of the primes for is a safe prime.
