• Previous palindromic prime concatenated with this palindromic prime is prime.at n=12A030463
• Palindromic Sophie Germain primes.at n=20A051835
• Palindromic primes with middle digit 7.at n=17A082443
• Fractal palindromic primes of first order.at n=11A082584
• Palindromic primes that yield a prime when sandwiched between two 7's. (Prefixing and suffixing a 'seven' on both sides yields another pal prime).at n=30A088271
