Since Fermat's last theorem has been proved, can it be that with powers greater than 2, the following functions can't all be simultaneously equal to zero with odd powers and all but one of them similarly with even powers? The functions are A^n Mod(B + C), B^n Mod(A  B), C^n Mod (A  B), (B^n +C^n) Mod A, (A^n  C^n) Mod B, (A^n  B^n) Mod C. A B and C being three different non zero integers and A the largest.

Is this of interest and is it well known?
