Every known cyclic Hadamard difference set has one of three types of v:(1) v=4n-1 is a prime. (2) v is a product of twin primes. (3) v=2n-1 for n=2,3,.. It is conjectured that all the cyclic Hadamard difference sets have parameter v which falls into one of the three types. The conjecture has been previously confirmed for n<10000 except for 17 cases not fully investigated. In this paper, four smallest cases among these 17 cases are examined and confirmed the conjecture for all vles/3435.
