Throughout, in a congruence such as xa= 1 (mod n) it will be assumed that x is prime to n. Then we have the theorem (1) œ^ a)= l (mod/1) for every prime p and integer a. For, by Fermâtes theorem,(1) is true when p is an odd prime and also when p= 2 and a= 1 or 2, in view of the definition of X. Then we have to examine only the case where p= 2 and a> 2. Now by Fermâtes theorem we have
