%N a(n) is the smallest (prime) integer such that the sequence {p_1, p_2, ..., p_n = a(n)} consists entirely of primes, where p_i = a(n)^(i/n).

%e a(8) = 967 because the sequence {2, 5, 13, 31, 73, 173, 409, 967} consists entirely of primes, the ith term in the sequence being Floor[967^(i/8)] and 967 is the smallest integer with this property.
