• Previous palindromic prime concatenated with this palindromic prime is prime.at n=5A030463
• Substrings from the right are prime numbers (using only odd digits different from 5).at n=35A032437
• Every suffix of palindromic prime a(n), containing no '0' digit, is prime (left-truncatable palindromic primes).at n=10A052023
• Every suffix of palindromic prime a(n) is prime (left-truncatable).at n=14A052024
• Palindromic primes whose sum of squared digits is also prime.at n=29A052035
• Smallest sets of 3 consecutive palindromic primes (palprimes) in arithmetic progression. The first prime of each set is listed.at n=3A059120
• Smallest palindromic prime with digit sum = n, or 0 if no such prime exists.at n=34A070245
• Palindromic primes with middle digit 3.at n=13A082439
• a(n) = smallest palindromic prime that begins with A082768(n) and contains more than twice the number of digits in A082768(n), or 0 if no such number exists.at n=33A082770
• Palindromic primes whose digit permutation yields at least one other palindromic prime.at n=13A082808
• Palindromic primes which are a member of a twin prime pair.at n=28A083840
• Palindromic primes p such that p+2 is also a prime: members of A083840 which are the smaller member of a twin prime pair.at n=16A083841
• Palindromic primes that yield a prime when sandwiched between two 1's. (Prefixing and suffixing a 1 on both sides yields another palindromic prime.)at n=13A088269
• Palindromic primes that yield a prime when sandwiched between two 3's. (Prefixing and suffixing a -three' on both sides yields another pal prime).at n=32A088270
• Duplicate of A088269.at n=13A103993
• Palindromic primes with squareful neighbors.at n=22A130870
• Palindromic primes using only odd digits (1, 3, 5, 7 or 9).at n=31A159471
• Palindromic primes starting with a digit 7.at n=26A222727
• Palindromic prime numbers == 8 (mod 9).at n=12A229881
• Primes p such that p^4 + p +/- 1 are twin primes.at n=32A236951
