• Value of C in y = x^2 + 9x + C such that y is prime for all x = 0 to 5.at n=31A097437
• Primes which are the reverse concatenation of two consecutive odd numbers.at n=22A104332
• Primes of the form 5*x^2 - 2*y^2, where x and y are successive natural numbers.at n=35A177077
• a(n) = n-1 for n <= 4, otherwise if n is even then a(n) = a(n-5)+2^(n/2), and if n is odd then a(n) = a(n-1)+2^((n-3)/2).at n=33A200310
