@bof Sorry! I meant the largest. Silly error!

comment finding numbers to make both sides equal
Either by solving $1000=x(x+1)(x+2)$ or by brute-force, you'll find out that $45$ is the smallest $x$ that works. So, anything below $45$ is fair game.

The set you describe is called the normalizer of $H$ in $G$. Check out proofwiki.org/wiki/Normalizer_is_Subgroup

comment Piecewise bijection $f: \Bbb R \to (\Bbb R$ \ $ \{1\})$
@user129120 Wow, My bad! For some reason, I thought you were asking for a function $f:\mathbb R \setminus \{1\}\to \mathbb R$. However, Since the function I proposed is a bijection, its inverse is a function from $\mathbb R \to \mathbb R \setminus \{1\}$. Kind of a cheat but still!

Is there a particular reason why you would need a piece-wise function? Then you could use $ \ f:x\to \frac 1{1-x}$.
