%N Consider primes p with a unique representation p = x^2 + y^2, where x is least primitive root of p. a(n) is the first such prime with x increasing in the sequence, x can be found in A082816.
%C A082842 includes all numbers having primitive roots.
%e 398261 = 10^2 + 631^2 and 10 is least primitive root of 398261.
%Y Cf. A001481, A002313, A082816, A082842.
