%N Primes of the form n^3 + 9.
%C Old name was "Primes of the form 8n^3 + 9".
%H Vincenzo Librandi, <a href="/A201262/b201262.txt">Table of n, a(n) for n = 1..6200</a>
%e Since 17 is prime and equal to 2^3 + 9, it is in the sequence.
%e Since 73 is prime and equal to 4^3 + 9, it is in the sequence.
%e 225 is not in the sequence, because, although it is 6^3 + 9, it is divisible by 5.
%t Select[Table[n^3 + 9, {n, 0, 248, 2}], PrimeQ]
