WebGenerators of the multiplicative group modulo. 2. k. In most books and lecture notes that explicitly give generators of the multiplicative group of the odd integers modulo 2 k, the set { − 1, 5 } is offered. However, the number 5 can be replaced by 3 which seems more logical for a standard choice. The proof I know do not suffer from these change. Web3 Answers Sorted by: 3 An element a ∈ Z / n Z is a unit if and only if ( a, n) = 1, that is, if and only if a and n are relatively prime. In your case, since the only prime divisor of n = 2 k is 2, this equivalence reduces to a is a unit if and only if a is odd. Hence, the elements of ( Z / 2 k Z) ∗ are 1, 3, 5, 7, …, 2 k − 5, 2 k − 3, 2 k − 1 fantasy church map https://shconditioning.com

I learned recently that the reason that g is commonly used to denote a primitive root is because it stands for "generator". I also know that this has something to do with the non-zero residues. However I don't understand how a g could be used to "generate" all non-zero residues. elementary-number-theory.

In fact, it can be shown that it's a cyclic group (of order p − 1 ), and has exactly ϕ ( p − 1) generators, where ϕ is Euler's totient function.

WebSep 3, 2013 · There are exactly $\phi(p-1)$ generators of the group, where $\phi(n)$ is Euler's totient function, the number of positive integers less than $n$ that are coprime to $n$. In our case for $p=11$, $\phi(p-1)=\phi(10)=\phi(2)\phi(5) = (2-1)\cdot (5-1) = 4$, and we see that we indeed have exactly 4 generators of the group, namely $(2,6,7,8)$.
