%N Starting primes for which there are no solutions in A097231.
%F a(n) = the n-th starting prime for which there are no solutions in A097231.
%e a(1) = 2 because there is no 3 X 3 square arrangement of the primes 2, 3, 5, 7, 11, 13, 17, 19 and 23 such that all row, column and diagonal totals are primes. a(2) = 23 because there is no 3 X 3 square arrangement of the primes 23, 29, 31, 37, 41, 43, 47, 53 and 59 such that all row, column and diagonal totals are primes.
%Y Cf. A097231 (number of distinct solutions for each starting prime), A097233 (starting primes with only one unique solution).
