Oct 31 comment $\left(\mathbb{Z}/p\mathbb{Z},\times\right)\cong\left(\mathbb{Z}/\left(p-1\right)\mathbb{Z},+\right)$? This made perfect sense. What would be required to show that $(\mathbb Z/p\mathbb Z)^\times$ is cyclic? Oct 30 asked $\left(\mathbb{Z}/p\mathbb{Z},\times\right)\cong\left(\mathbb{Z}/\left(p-1\right)\mathbb{Z},+\right)$?

Sep 10 asked Arbitrary Intersection of Bounded Sets Is Bounded Jul 25 comment Basis, Ordered Basis, and Linear Independence @SolidSnake, if you write your comments into an answer, then I will accept it. Thank you. Jul 25 comment The Matrix of $T$ Relative to the Ordered Bases $\mathcal B$ and $\mathcal B'$ for $V$ I know $[T\alpha]_{\mathcal B'}=A[\alpha]_{\mathcal B}\not\Longleftrightarrow[T\alpha]_{\mathcal B}=A[\alpha]_{\mathcal B'}$ because neither $[T\alpha]_{\mathcal C}$ nor $[\alpha]_{\mathcal C}$ might even make sense for some $\mathcal C\in\{\mathcal B,\mathcal B'\}$. What I'm concerned about is whether the bolded definition is ambiguous with my restrictions.

What if it is an ordered basis? Jul 25 asked Basis, Ordered Basis, and Linear Independence Jul 24 comment Matrix Equation: Reduced Row Echelon Form Brilliant! I also see the connection between this and Solid Snake's comment regarding elementary matrices.
