 Dec10 awarded Caucus Oct28 comment finding numbers to make both sides equal @bof Sorry! I meant the largest. Silly error! Oct28 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. Oct17 comment Solving an exercise in Pinter's Abstract Algebra The set you describe is called the normalizer of $H$ in $G$.

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! May1 comment Piecewise bijection $f: \Bbb R \to (\Bbb R$ \ $\{1\})$ Is there a particular reason why you would need a piece-wise function? Then you could use $\ f:x\to \frac 1{1-x}$.
