Answer 1

You can't have any .github.io subdomain. The subdomain has to be either your username or an organization name. So you could have limedf.github.io, or make an organization and have orgname.github.io. You could try to get an organization named cubes, but I'm pretty sure that would already be taken.

Answer 2

404 means the page you are requesting doesn't exist.
