[p] **Fermat's theorem** by akdevaraj Jan 27Fermat's theorem works even if the base is a Gausssian integer subject to a) the prime under consideration is of shape 4m+1
and b) the exponent and base are co-prime.
((2+3*I)^16-1)/17
= -47977440 - 803040*I

This could be an example to here, the normal.

Hence, k0 from (b) process !.

[p] **real name?** by WM 16-10-29You are right. I have included your statement into
https://www.hs-augsburg.de/~mueckenh/Transfinity/Transfinity/pdf
Would you disclose your real name?
