Properties

Appears in sequences

• Primes which can be expressed as sums of distinct powers of 8.at n=15A077722
• 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=34A090718
• Primes whose base-8 representation also is the base-2 representation of a prime.at n=13A235465
• a(n) = Sum_{d|n} n^(d-1).at n=7A308814
• a(n) = Sum_{d|n} 8^(d-1).at n=7A339688
