• Numbers k such that 2*3^k + 35 is prime.at n=40A059768
• Integer part of (Product(n^((1 + log(1 + i))/i^2), {i, 1, n})).at n=26A062486
• Nearest integer to (Product(n^((1 + log(1 + i))/i^2), {i, 1, n})).at n=26A062487
• Primes of the form n followed by the least k == 1 (mod n).at n=38A090920
• Primes with at least one of each odd digit and no even digits.at n=12A108418
• a(n) = 4*a(n-1) + 13*a(n-2) for n>2, a(1)=1, a(2)=4.at n=6A200069
• Primes of the form (n^2+1)/26.at n=26A208292
• Primes p with each odd decimal digit present at least once.at n=12A232447
• a(n) = a(n-2) + a(n-1) if that sum is prime. Otherwise, a(n) = a(n-2) + a(n-1) + prime(m-1) + prime(m-2) + ... + prime(s), where a(-1) = a(0) = prime(0) = 1, m = pi(a(n-2)), and s = max(0, 1, 2, ..., m-1) such that the sum is prime.at n=11A337347
