Constructing Nearfields

      Dickson Nearfields

            DicksonPairs(p, h1, v1) : RngIntElt, RngIntElt, RngIntElt -> SeqEnum
            DicksonTriples(p, hb, vb) : RngIntElt, RngIntElt, RngIntElt -> SeqEnum
            Example FldNear_dicksonpairs (H23E1)
            NumberOfVariants(q, v) : RngIntElt, RngIntElt -> RngIntElt
            NumberOfVariants(N) : NfdDck -> RngIntElt
            VariantRepresentatives(q, v) : RngIntElt, RngIntElt -> SeqEnum
            Example FldNear_variants (H23E2)
            DicksonNearfield(q, v : parameters) : RngIntElt, RngIntElt -> NfdDck

Operations on Elements

      Nearfield Arithmetic

      Equality and Membership

      Parent and Category
            N ! x : Nfd, FldFinElt -> NfdElt
            ElementToSequence(x) : NfdElt -> SeqEnum

      Predicates on Nearfield Elements

Operations on Nearfields
      Cardinality(N) : Nfd -> RngIntElt
      Random(N) : Nfd -> NfdElt
      Identity(N) : Nfd -> NfdElt
      Zero(N) : Nfd -> NfdElt
      PrimeField(N) : Nfd -> FldFin
