COMMENTS
| Intersection of A002145 Primes of form 4n+3 and A003627 Primes of form 3n-1. So these are both Gaussian primes with no imaginary part and Eisenstein primes with no imaginary part. - Alonso Delarte (alonso.delarte(AT)gmail.com), Mar 29 2007
Is this the same sequence as A141187 (apart from the initial 3)?
