Since you claim every line is necessarily finite, but the number of lines is not, there will be a number of lines greater than the number of digits in your finite first line.
When you have more lines than you have digits in your first line, and, you claim fails! > > > > But none of this is relevant, because we've explicitly defined the > > antidiagonal d and it is a triviality to see that it is an infinite > > sequence of nonzero and nonnine digits.

No, YOU are the one trying to do that. Our N is ACTUALLY infinite

You may be but we are not.

Assume we are not.

Any function from N to {0,1,2,3,4,5,6,7,8,9} leaves that domain. And everywhere but in WMytheology such functions exist.
For example, the decimal form of 1/3. > > > > > Do you agree that (by presumption) t_i is defined for every i in N? > > Of course! Why not? Isn't every i in N finite?
Do you claim that N is finite? Note that being not finite means being infinite. > > > > I don't want to imagine what you are thinking, because I will risk > > getting it wrong.

But N is not. And in ZF there is an axiom providing for a set which is not finite. > > > > > Look, presently we work in the system of terminating decimals  by > > > definition.
You may be but no one else is. That is one of your your troubles, you claim that everyone makes the assumptions that you make, but that is false.

It would be even nicer if you could be clear enough so that Jesse could understand it in one reading. Then maybe others could understand it too.

One cannot even write down very large naturals in decimal notation, but that does not mean that they do not exist.
So WM is WRONG!
