We have lots of reason to beeive that anything WM presents as a proof that is not copied from soemone more competent, is incorrect.
Some of those reasons are the obvious flaws in logic that WM is know for. > > > > > Clearly, for all j, d(j) != t_j(j) and hence d != t_j for any j in > > N. > > > > Is this what you mean up 'til now? > > Yes. > > > > > > 4) Certainly you agree that, since all t_i = (t_i1, t_i2, ..., t_in) > > > have only a finite, though not limnited, number n of digits, the > > > diagonalization for every t_i yields a finite d_i =/= t_ii. > > > (The i on the left hand side cannot be larger than the i on the right > > > hand side.

In decimal notation, one could start with 10 lines of length 1 followed by 90 lines of length 2, followed by 900 lines of length 3, etc., and never repeat a number.

But a "diagonal" need not be, and will not be finite. > > > > Here are some obvious things. > > > > d(j) is defined for every j in N. > > d(j) != 0 and d(j) != 9 for any j in N. > > > > Hence the number d does not have a terminating decimal > > representation. > > Neither the set of t_i does have a largest element.

The diagonal is already required to be infinitely long, so its length need not change.
