Method of Discriminating a Class of Special Prime NumbersDOI: 10.4236/oalib.1115937, PP. 1-6 Keywords: Wieferich Prime Number, Detemination Method, Sufficient and Necessary Conditions, Fermat Quotient, Euler Quotient Abstract: It is very difficult to find a new Wieferich prime number. This paper uses Eisenstein congruence formula and Sun Zhihong congruence theorem to a method to determine Wieferich prime number. The Fermat quotient and Euler quotient are also studied in the paper.
