Properties

Appears in sequences

• Smallest denominator of fraction using palindromes that approximates 'e' to at least n digits after the decimal point.at n=5A048432
• Palindromic primes with middle digit 5.at n=20A082441
• Palindromic primes whose digital root equals their middle digits.at n=11A082518
• Palindromic primes p such that if each digit d is replaced by 10-d then the resulting palindrome is also a prime.at n=26A088092
• 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=17A088269
• Palindromic primes whose squares are the sum of three consecutive primes.at n=12A130704
• Palindromic primes having both a prime middle digit and a prime digital root.at n=34A157869
• Palindromic primes p = q//r//q such that q and r are also palindromic primes.at n=14A177678
• Palindromic prime numbers == 5 (mod 9).at n=25A229879
• Palindromic primes of the form p//q//reverse(p), where p is a prime (not necessarily palindromic) and q, of course, is a palindromic prime.at n=23A343714
• Palindromic primes of the form p//q//reverse(p), where p, q, and reverse(p) are primes.at n=19A343715
• Palindromic primes having at least one different anagram that is also a palindromic prime.at n=14A345869
• Prime numbersat n=91168
