Properties

Appears in sequences

• Palindromic primes containing at least one pair of consecutive equal digits.at n=25A050786
• Let p = abc..k be a prime in base 10. Define mirror(p) = abc...k...cba. Sequence gives primes of the form mirror(p) for some p.at n=27A068686
• Palindromic primes with middle digit 9.at n=10A082445
• 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=26A083841
• Palindromic primes with nondecreasing digits up to the middle and then nonincreasing.at n=38A084836
• Smallest palindromic prime built using the palindromes with odd number of digits as central digits.at n=28A087364
• Palindromic primes p such that if each digit d is replaced by 10-d then the resulting palindrome is also a prime.at n=23A088092
• Palindromic primes that yield a prime when sandwiched between two 9's.at n=28A088272
• Smallest palindromic prime p, larger than previous term, such that concatenation of n and p is a prime.at n=19A103836
• Smallest palindromic prime containing the n-th palindrome as central digit(s), or 0 if no such prime exists.at n=38A195294
• Smaller of two consecutive palindromic primes whose product of digits is equal and nonzero.at n=1A227892
• Palindromic prime numbers == 8 (mod 9).at n=20A229881
• Palindromic primes in A380943.at n=17A383815
• Prime numbersat n=87828
