WebA unit g ∈ Z n ∗ is called a generator or primitive root of Z n ∗ if for every a ∈ Z n ∗ we have g k = a for some integer k. In other words, if we start with g, and keep multiplying by g eventually we see every element. Example: 3 is a generator of Z 4 ∗ since 3 1 = 3, 3 2 = 1 are the units of Z 4 ∗. Example: 3 is a generator of Z ...
