• Smallest palindromic prime that ends (on the least significant side) in prime(n).at n=23A082625
• Smallest palindromic prime that ends (the least significant side) in (2n-1) the n-th odd number, or 0 if no such number exists, e.g., for 2n-1 = 10k + 5, k>0.at n=44A082626
• a(n) = smallest palindromic prime that begins with A082768(n), or 0 if no such number exists.at n=42A082769
• Palindromic primes p such that p-2 is also a prime: members of A083840 which are the larger member of a twin prime pair.at n=16A083842
