How to prove existence of homeomorphism from the Cantor set onto itself

68 Views Asked by At

Prove that if $x$ and $y$ are distinct points in the Cantor set $C$, then there is a homeomorphism $h$ of $C$ onto $C$ such that $h(x)=y$.

This question was asked in my analysis quiz and I was unable to prove it. I am unable to think about such a map. Can you please help me with that?

I will work rest of details by myself.
