Gaussian Prime
Gaussian primes are Gaussian integers 
satisfying one of the following properties.
1. If both 
and 
are nonzero then, 
is a Gaussian prime iff 
is an ordinary prime.
2. If 
, then 
is a Gaussian prime iff 
is an ordinary prime and 
.
3. If 
, then 
is a Gaussian prime iff 
is an ordinary prime and 
.
The above plot of the complex plane shows the Gaussian primes as filled squares.
The primes which are also Gaussian primes are 3, 7, 11, 19, 23, 31, 43, ... (OEIS A002145). The Gaussian primes with

The cover of Bressoud and Wagon (2000) shows an illustration of the distribution of Gaussian primes in the complex plane.
As of 2009, the largest known Gaussian prime, found in Sep. 2006, is 
, whose real and imaginary parts both have 
decimal digits and whose squared complex modulus has 
digits.
