"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 ... " - Phi in number theory

WebWe know y is a unit if and only if y and n are coprime. So the size of Z n ∗ is precisely the number of integers in [ 1.. n − 1] that are coprime to n. We write ϕ ( n) for the number of elements of Z n ∗ . The function ϕ ( n) is called the Euler totient function . Actually, it turns out to be convenient to have ϕ ( 1) = 1, so we prefer ... WebThe Euler phi function , also known as the Euler totient function , is defined as the function \phi:\mathbf {N}\rightarrow\mathbf {N} (that is, taking values in the natural numbers and giving values in the natural numbers) where \phi (n) is the number of natural numbers less than or equal to n that are coprime to n.
