Properties

Appears in sequences

• Initial members of prime triples p < q < r such that r-q = n*(q-p).at n=9A181994
• Primes p = 1 mod 6 such that all three iterations p=(6p+1) give primes = 1 mod 6.at n=31A210686
• Primes of the form p==3 (mod 4) such that the average of their primitive roots equals p/2.at n=24A267010
• a(n) is the least prime p such that the second forward difference of three consecutive primes p, q and r is n = (p - 2q + r)/2.at n=27A316791
• Bemirps that also interpret 2 and 5 as upside-down forms of each other, assuming a digital font.at n=21A335731
