Primitive root of 12
WebLemma 2.2. (Primitive root test) An integer u∈ Zis a primitive root modulo an integer n∈ N if and only if uϕ(n)/p−1 ≡ 0 mod n for all prime divisors p ϕ(n). The primitive root test is a special case of the Lucas primality test, introduced in [27, p. 302]. A more recent version appears in [11, Theorem 4.1.1], and similar sources ... WebThe nth cyclotomic polynomial is the minimal polynomial for the nth primitive roots of unity, i.e. for each primitive nth root , n(x), the monic polynomial with integer coe cients of minimum degree with as a root. 10.(Geometry) The roots of unity form the vertices of a regular n-gon on the unit circle in the complex plane.
