%S A168219  1,3,4,6,15,16,18,24,27,30,31,36,37

%N A168219 Naturals n for which 1 + 10*n^3 is prime

%C A168219 (2) It is an open problem if 3 consecutive naturals n exist which give such a prime.

Me: All terms == {0,1} mod 3 => hence no 3 consecutive naturals n can give primes.

I leave rewording and submitA to someone with better math/Eng than me, 

Thanks, Zak
