A new prime p for which the least primitive root (mod p) and the least primitive root (mod p^2) are not equal
Abstract
With the aid of a computer network we have performed a search for primes p<10^{12} and revealed a new prime p=6692367337 for which its least primitive root (mod p) and its least primitive root (mod p^2) are not equal.
