OEIS Sequences

a(n) = 4·n² - 10·n + 7. A54554

a(n) = a(n-1) + a(n - 1 - number of even terms so far). A6336

a(n) = p² + p + 1 where p runs through the primes. A60800

a(0)=0, a(1)=1, a(2)=1, a(3)=1, a(n) = a(n-3) + a(n-4) for n > 3. A79398

a(1) = 5; a(n) is smallest number >= a(n-1) such that the juxtaposition a(1)a(2)...a(n) is a prime. A46255

T(n,k)=Number of (n+2)X(k+2) 0..1 arrays with each 3X3 subblock having clockwise perimeter pattern 00000001 00000101 or 00010001. A260177
