WebWhen ( Z / nZ) × is cyclic, its generators are called primitive roots modulo n . For a prime number p, the group ( Z / pZ) × is always cyclic, consisting of the non-zero elements of the finite field of order p. More generally, every finite subgroup of the multiplicative group of any field is cyclic.
