%N A084732 Let p be the n-th prime; Cp(x) be the p-th cyclotomic polynomial (x^p-1)/
               (x-1); a(n) is the first prime Cp(x) after Cp(1).
%C A084732 A084732(k) = A085399(prime(k))
%e A084732 a(5)=12207031 because 11 is the 5th prime; C11(x) is composite for x=2,
               3,4 and C11(5)=12207031 is prime.
