Feb 13 accepted Powers of a greatest common denominator Feb 13 asked Is the Euler phi function bounded below? Feb 6 comment Finding the order of elements in a group? Alright, so I picked up where you left off, and I found the following. $[4]^2 = [16]$, so $n = 2$ does not work. However, $[4]^{11} = [1]$, so $n = 11$ and since $11$ is least, then the order of $[4]$ is 11. Am I correct? Feb 6 accepted Finding the order of elements in a group? Feb 6 comment Finding the order of elements in a group? Thank you so much for the clarification! I think I understand this problem now. Feb 6 comment Finding the order of elements in a group? Yes, that is the exact question. Sorry for any confusion, I thought I might have had to clarify some of my notation. Feb 6 awarded Editor Feb 6 comment Finding the order of elements in a group? The first part of my question IS the question I am asking. I simply do not know how to begin, and I am trying to seek help as well as provide background info on what we have learned prior to this.

Feb 6 comment Finding the order of elements in a group? Sorry, I was trying to define as much as I can while still keeping things terse. "For any sets $X, Y$ and any function $f: X \to Y$, there exists an equivalence relation defined on $X$, $Ker(f)$. Also, $X / Ker(f) = \{[x] | x \in X\}$ where for $x \in X$, $[x] = \{y \in X | f(y) = f(x)\}$". Feb 6 asked Finding the order of elements in a group? Jan 30 asked Fermat Numbers as a product
