%N A297356 Values of n for which pi_{12,7}(p_n) - pi_{12,1}(p_n) = -1, where p_n is the n-th prime and pi_{m,a}(x) is the number of primes <= x which are congruent to a (mod m).
%C A297356 This is a companion sequence to A297357 and includes the values of n for the first discovered sign-changing zone for pi_{12,7}(p) - pi_{12,1}(p) prime race. The full sequence checked up to 10^14 has 55596 terms (see b-file).
