I think this is taking it too far. The property of being prime, odd or
even is a property of natural numbers, not of cardinal numbers
(actually being prime is a property of a ring and the cardinal numbers
are NOT a ring, they're not even a set). It is like the question:
"What's the horsepower of your pencil?" or "What's the sound of the
blue color?" Don't let Tony drag you into this formalism masturbation
where properties and operations of natural/real numbers are applied to
strange objects to derive nonsensical results.
