Transfinite arithmetic --- Introduction ---

This is an exercise as well as a game. Let a set E of k elements in the finite ring ZZ/nZZ, represented by k integers between 0 and n-1. For any element t in ZZ/nZZ, the addition or multiplication by t transforms E into another set Et subset ZZ/nZZ.

Thus the exercise generates two sets E,F subset ZZ/nZZ, of the same number of elements, and asks you to transform E into F by successive additions and multiplications by elements of ZZ/nZZ. And you will be scored according to the number of steps you make.
