abstract = {Arithmetic properties of some families in              F        l    [  x  ]      /    ⟨      x                  p        s                    q        t              −  1  ⟩ were obtained by using the cyclotomic classes of order 2 with respect to    n  =      p    s        q    t  , where    p  ≡  3        m    o    d      4,    gcd  (  ϕ  (      p    s    )  ,  ϕ  (      q    t    )  )  =  2,    l is a primitive root modulo        q    t  , and              o      r      d                      p        s              (  l  )  =  ϕ  (      p    s    )      /    2. The form of these cyclotomic classes enabled us to further generalize the results obtained in [1]. The explicit expressions of primitive idempotents of minimal ideals in              F        l    [  x  ]      /    ⟨      x                  p        s                    q        t              −  1  ⟩ were also obtained.}
