Well, "something as big as Rayo's Number" would obviously have to be Rayo's number. Anything else would not either bigger or smaller,and therefore not "something as big" ;-)

At any rate, I agree that merely multiplying numbers of this size is silly. For all purposes, BOX would be indistinguishable from X.
