OEIS Sequences

Initial term in sequence of four consecutive primes separated by 3 consecutive differences each <=6 (i.e., when d=2,4 or 6) and forming d-pattern=[2, 6,6]; short d-string notation of pattern = [266]. A78849

Least prime p such that pⁿ + 1 is the product of n distinct primes. A280005

T(n,k)=Number of nXk 0..1 arrays with every element equal to 0, 1, 2, 3, 6 or 7 king-move adjacent elements, with upper left element zero. A299180

a(n) is the least prime p such that the number of distinct prime factors of pⁿ + 1 sets a new record. A362957

Partial sums of primes, but with a twist. A247657

Least k such that kⁿ + 1 is the product of n distinct primes (k > 0). A281940

Primes p such that the differences between the 5 consecutive primes starting with p are (2,6,6,6). A78951

Eighth prime p such that (p+n)²+n is prime but (p+j)²+j is not prime for all 0<j<n. A238680

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 from merging of 5 successive digits in decimal expansion of cos(1). A104961
