Properties

Appears in sequences

• Let p run through the primes; write p in base 10 and then interpret it in base 128 getting a number q; if q is prime then adjoin q to the sequence.at n=26A090718
• a(1)=1. a(n) = the smallest integer > a(n-1) that is an (odd) palindrome when written in binary, and is such that (a(n)-a(n-1))/2 is prime.at n=20A161536
• Prime lucky numbers that are palindromic in base 2.at n=18A244114
• Prime partial sums of the primes == 5 (mod 6).at n=16A354573
