OEIS Sequences

Primes which can be expressed as sum of distinct powers of 7. A77721

a(0) = 16, after which, if (2·a(n-1)) - 1 = ∏_{k >= 1} (p_k)^c_k then a(n) = ∏_{k >= 1} (p_k-1)^c_k, where p_k indicates the k-th prime, A000040(k). A246345

Primes of the form 7n² + 1. A201602

Primes of the form 8k+1 generated recursively. Initial prime is 17. General term is a(n)=Min {p is prime; p divides (2Q)⁴ + 1}, where Q is the product of previous terms in the sequence. A125039

Primes of the form 2^a * 5^b * 7^c + 1 for positive a, b, c. A114992
