Both of you lose this argument.  All irrational numbers, for example,  
"break" every copyright that could possibly exist.  For example, you  
can find any arbitrary sequence of Base-N digits when you express PI  
in base-N form.  I can simultaneously express both the laws of  
physics (not copyrightable) and the latest episode of the TV show  
"Numbers" (thoroughly copyrighted) as numbers.  In fact, we do both  
all the time (you can express both the latest equations for  
theoretical physics and a TV show as bits (IE: numbers) on an HDD.   
Ergo "$FOO is a number" says *NOTHING* about whether or not copyright  
applies to $FOO.  In case you haven't noticed, the whole damn point  
of math is that you can express *EVERYTHING* as numbers, albeit maybe  
horribly unbelievably complex ones.

Now, back to actual legal issues: Since most copyright laws  
explicitly prevent copyrighting of pure math, the only actual  
protection you have for some collection of so-called numbers is  
whether or not the numbers *REPRESENT* something which may be  
copyrighted.  Furthermore, copyright has _always_ been independent of  
representation; a person owns copyright on a book regardless of  
whether it's hardback, softcover, digital, memorized, etc.  The  
person who owns the copyright on a book is able to prevent someone  
who has memorized the book from giving public recitals of said book,  
and the neuron-linkage-based storage the brain uses is about as far  
as you can possibly get from twiddling magnetic bits on a disk drive  
or dumping carbon-based inks on a page made of plant cellulose.
