I was given this puzzle, and told it cannot be solved using Unix:

You have a file that needs protected from prying eyes.  You must allow
only 5 people read access, and 4 people read/write access.  The rest of
the world cannot be allowed to view it.  What set of Unix permissions
and ownership can support this?
