1. ## Compactness

Assume $M$ is compact, non-empty, perfect, and homeomorphic to its Cartesian square, $M \simeq M \times M$. Must $M$ be homeomorphic to the Cantor set, the Hilbert Cube, or some combination of them?

Hints are appreciated.

Thanks

2. I think that $M$ must be homeomorphic to a combination of the two.

3. Is this a hard problem in general?

It demands some level of mathematical sophistication.

If you want to try out the proof of the answer you gave, I think there are people here who will be able to critique it.

5. To be honest, I know I'm curious as to how shilz222 is going to combine the Cantor set and the Hilbert cube...
