a(n) = ∑_k=1..n T(n,k), array T as in A049790. A49791

Primes of the form 6k - 1 preceding the first-occurrence gaps in A334543. A334544

Numbers n which are prime and which when each digit is incremented by 2 with carries ignored yields another prime p with the same property. A88786

a(0)=1, a(1)=1, a(n) = 9·a(n/2) for even n >= 2, and a(n) = 8·a((n-1)/2) + a((n+1)/2) for odd n >= 3. A116526

a(n) = 36·n² - 810·n + 2753, producing the conjectured record number of 45 primes in a contiguous range of n for quadratic polynomials, i.e., abs(a(n)) is prime for 0 <= n < 44. A117081
