• Palindromic primes in which parity of digits alternates.at n=32A030150
• Greater of two consecutive palindromes, both of which are prime.at n=21A032594
• Undulating primes (digits alternate).at n=45A032758
• Primes with consecutive digits that differ exactly by 5.at n=9A048402

• Undulating palindromic primes: numbers that are prime, palindromic in base 10, and the digits alternate: ababab... with a != b.at n=21A059758
• Palindromic primes with middle digit 9.at n=8A082445
• Palindromic primes using only nonprime digits (0,1,4,6,8,9).at n=17A083185
