Finding generators of cyclic groups
WebJan 31, 2015 · For any non identity element a in the group, we know a^ {p-1}=1 (mod p) by Fermat's little theorem. Hence all the elements except 1 are generators. Cite 1 Recommendation 31st Jan, 2015 Cite... 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 ...
