That is wrong. You have no reason to believe that your definition of

You will have have recognized that here the diagonal argument is
applied. It is obvious that up to every line = column the list is a
square.

Every t_i is finite. Hence, in a square, if the width is finite, also
the length must be finite.

Neither the set of t_i does have a largest element. Nevertheless there
is no t_i of actually infinite length.

A sequence of squares will never result in a square such that all
sides are finite but the diagonal d is infinite. The overlap of d and
t_i cannot be larger than t_i.
In particular, what would be changed in the length of d if we admitted
also non-terminating t_i (of infinite length)?
