Properties

Appears in sequences

• Let p = n-th odd prime. Then a(n) = least prime congruent to 5 modulo 8 such that Legendre(a(n), q) = -1 for all odd primes q <= p.at n=17A001992
• a(n) gives least prime for which the n-th prime is the least prime which is not a primitive root of a(n) (see A060084), or 0 if the n-th prime never occurs in A060084.at n=19A060085
• Records in A001992.at n=12A094852
• Increasing sequence of primes p such that all of 2,3,5,...,prime(n) are primitive roots mod p.at n=17A213052
• a(n) is the least prime p = prime(k) > prime(n) such that A306530(k) = prime(n).at n=19A307965
• Prime numbersat n=4063225
