Content Summary

Euler presents a third proof of the Fermat theorem, the one that lets us call it the Euler-Fermat theorem; this seems to be the proof that Euler likes best. He also proves that the smallest power xn that, when divided by a number N, prime to x, and which leaves a remainder of 1, is equal to the number of parts of N that are prime to n. In other words, the order of x modulo N is equal to the number of distinct aliquot parts of N.
