I'd like to see an example, this sounds like some kind of rhetorical imaginary paradox to me.
If I don't know the names of my great-great-great-great-great grandfathers, I would assign numbers or some kind of code to them. I couldn't guarantee that there were exactly 64 of them but I could be sure that I had at least one. However many of them, I don't see how those identifiers would fall outside of, say, a genealogy "UoD". Or do you mean something else?
(I'd still like to know what the "hack" is, too.) Received on Thu Nov 13 2008 - 04:23:14 CET
