Fermat Quotient
The Fermat quotient for a number 
and a Prime base 
is defined as
 | (1) |
, then |  |  | (2) |
 | |  | (3) |
 | |  | (4) |
all (mod
). The quantity 
is known to be Square for only two Primes: the so-calledWieferich Primes 1093 and 3511 (Lehmer 1981, Crandall 1986).See also Wieferich Prime
