Recent edits
The recent edits over the last couple of days don't seem to have added much, in fact they seem to obscure the flow.
For a start:
- Let $g \in H$ and $x \in H \cap N$.
- However, $H \le G$ and $ g \in H$ imply:
- $g \in G$
don't add anything. $g$ is a dummy variable in $\forall n \in N: \forall g \in G: g n g^{-1} \in N$, which is a direct implementation of the definition of normal subgroup.
The rest of the proof similarly.
Can the reasoning behind these edits be explained? --prime mover (talk) 15:46, 17 December 2023 (UTC)
