Properties

Appears in sequences

• Numbers k such that 65*2^k+1 is prime.at n=43A032382
• Palindromic terms from A019546.at n=16A045336
• Palindromic primes that are "near miss circular primes" (all cyclic shifts except one are primes).at n=10A045978
• Palindromic primes with strictly decreasing digits up to the middle and then strictly increasing.at n=13A062352
• Palindromic primes = 1 mod 4.at n=36A081220
• Palindromic primes with middle digit 2.at n=9A082438
• Palindromic primes whose digit permutation yields at least one other palindromic prime.at n=12A082808
• Palindromic primes with nonincreasing digits up to the middle and then nondecreasing.at n=14A084837
• Smallest palindromic prime built using the palindromes with odd number of digits as central digits.at n=31A087364
• 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=27A088270
• Palindromic primes that yield a prime when sandwiched between two 9's.at n=17A088272
• Chen primes p such that p is palindromic.at n=35A109574
• Primes prime(n) such that n and prime(n) have only prime digits.at n=9A167483
• Palindromic primes that are the average of the members of emirp pairs.at n=16A178583
• Smallest positive integer which cannot be calculated by an expression containing n binary operators (any of add, subtract, multiply and divide) whose operands are any integer between 1 and 9; parentheses allowed.at n=7A181898
• Smallest palindromic prime containing the n-th palindrome as central digit(s), or 0 if no such prime exists.at n=41A195294
• Palindromic primes starting with a digit 7.at n=13A222727
• Palindromic prime numbers == 4 (mod 9).at n=11A229499
• 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=15A343714
• Palindromic primes of the form p//q//reverse(p), where p, q, and reverse(p) are primes.at n=14A343715
