OEIS Sequences

Prime numbers p that yield a new record for the least number k such that p·k + 1 and p·k - 1 are twin primes. A220141

Numbers n that yield a new record for k such that n·k+1 and n·k-1 are twin primes. A220143

P(n,k) is an array read by rows, with n > 0 and k=1..5, where row n gives the chain of 5 consecutive primes {p(i), p(i+1), p(i+2), p(i+3), p(i+4)} having the symmetrical property p(i) + p(i+4) = p(i+1) + p(i+3) = 2·p(i+2) for some index i. A267028

Where records occur in A124522. A124743

Primes of the form 34k+1 generated recursively. Initial prime is 103. General term is a(n) = Min {p is prime; p divides (R¹⁷ - 1)/(R - 1); p == 1 (mod 17)}, where Q is the product of previous terms in the sequence and R = 17·Q. A125038

Let H(n) be the reduced fraction ∑_i=1..n 1/i. a(n) is the least factor of H(n)'s numerator or denominator that doesn't divide either part of any earlier H(m). A113571
