OEIS Sequences

Primes p such that 2^p-1 and the p-th Fibonacci number have a common factor. Prime terms of A074776. A80050

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

Primes of the form prime(nk) followed by prime(k). A89788

Real fixed point of the function sin(cos(x)) between x=0 and x=1. A131691

a(1) = 1, a(2) = 2, then a(n+1) is the smallest number such that the highest common factor of a(n) and a(n+1) is different from that of a(n) and a(n-1) and is more than 1. A76919
