....H is a subset of I , the set of coset leaders of the cyclotomic cosets modulo p. Here we always suppose that 1 2 H . Let B i;t = Tr m t 1 (fi t ff it ) andB t = fB i;t g i0 : 4) Then A = P t2H B t . A useful discussion of these facts is given in [3] The following results were proved in [2]. Theorem 1 A pair ( 0 ) is a trinomial pair of the sequence fa i g if and only if ff is a root of F t (x) 1 x) t 1 x t (5) for each t 2 H and ( 0 ) satisfies 1 ff = ff 0 . Corollary 1 If ( 0 ) is a trinomial pair of the sequence fa i g, then ( 2 j ; ....
....2 are called the regular trinomial pairs of fa i g; other trinomial pairs are called non regular trinomial pairs of fa i g. 3 A Conjecture For all n 3, there exist regular trinomial pairs. A complete search for 3 n 17 was carried out by Golomb and Gong; there are tables for 3 n 12 in [2]. Recall that I is the set of coset leaders modulo 2 n Gamma 1. For t and 2 I , we define two maps on GF(2 n ) as follows, Add 1 map : A(ff) 1 ff; Power map : P t (ff) ff t : Notice that P t AP (ff) 1 ff ) t ; 6) AP t P (ff) 1 ff t ; 7) and P t P = ....
