Properties

Appears in sequences

• Palindromic primes of the form 'primemirp' resulting from A054217.at n=21A054218
• 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=31A068686

• Palindromic primes with middle digit 1.at n=7A082436
• Smallest 2n-1 digit palindromic prime with digit sum of 2n-1, or 0 if no such number exists.at n=1A083438
• Palindromic primes p such that p-2 is also a prime: members of A083840 which are the larger member of a twin prime pair.at n=20A083842
• Palindromic primes pp such that 9876543210pp0123456789 is palindromic prime.at n=12A103834
