Hi unlord, can you please switch the search engin on?

## Fermat's theorem in Z(i)

So far I have been giving examples only. Now let me generalise: Let p’ be a prime of shape 4m+1 Then (n + k*i) is a base for application of Fermat’s theorem in Z(i). Here both n and k belong to N excepting cases where (n+k*i) is a factor of p’.
