Abstract:
    In this paper, we will introduce theorem, which will generate Fermat Pseudo primes in different base system. Also, by fixing base-2, we find first poulet number and we show the first square type poulet number by suitable example and theorem.
Keywords:
    Fermat’s Little Theorem, Poulet Number
