 G. Löh, "Long chains of nearly doubled primes," Math. Comp., 53 (1989) 751759. MR 90e:11015
Abstract:
A chain of nearly doubled primes is an ordered set {a_{1}, a_{2}, . . . , p_λ } of prime numbers, interlinked by a_{k} = 2 a_(k1) ± 1. A search for long chains of this kind has been performed in the range a_{1} < 2^{50}. Chains of length up to 13 have been found. Shorter chains have been counted in some restricted ranges. Some of these counts are compared with the frequencies predicted by a quantitative version of the prime ktuple conjecture.
[Chains of primes for which each is either twice the proceeding one plus one, or each is either twice the proceeding one minus one. See also [Guy94, section A7].]
