%N Primes with primitive root 99.

%C To allow primes less than the specified primitive root m (here, 99) to be included, we use the essentially equivalent definition "Primes p such that the multiplicative order of m mod p is p-1". This comment applies to all of A019334-A019421. - _N. J. A. Sloane_, Dec 03 2019
