....(mod 2) if = 2 r Gamma 1. Note that primitivity is a stronger condition than irreducibility 1 , i.e. Q(t) primitive implies that Q(t) is irreducible, but the converse is not generally true unless 2 r Gamma 1 is prime 2 . Tables of irreducible and primitive trinomials are available [4, 10, 14, 16, 20, 22, 23, 24, 25]. In the following we usually assume that Q(t) is irreducible. Our assumption that q 0 and q r are odd excludes the trivial case Q(t) t, and implies that Q(t) is irreducible (or primitive) of degree r iff the same is true of Q(t) We are interested in the period pw of the sequence (x n ) ....

....most r Gamma 1 determined by the initial values U 0 ; U r Gamma1 . For example, if m = 2 and the initial values are not all zero, then the sequence has maximal period 2 r Gamma 1 if and only if Q(x) is a primitive polynomial (mod 2) Tables of such primitive polynomials are available [36, 37]. Verification is particularly simple if r is the exponent of a Mersenne prime (i.e. 2 r Gamma 1 is prime) because then we only need to check that x = x 2 r mod (Q(x) 2) which can be done by r squarings of polynomials (mod 2) involving a total of only O(r 2 ) operations [38] The more ....
