I do not construct the tree by means of unions. Every finite path that is constructed *replaces* its predecessor (there is always only one predecessor, because the others had been removed before). And obviously a finite path can never produce an infinite path, can it? > > More cannot be > > > distinguished by nodes.

It is very easy to replace the Binary Tree by a decimal one. If you have trouble to calculate the decimal from the given binary, then simply start with decimal paths in a decimal tree. > > > that can be applied in mathematics and in Cantor's diagonal argument. > > We can neither distinguish nor apply by digits more than all > > terminating decimal fractions.

Moreover, he has proved that even in the set of all finite binary or decimal sequences there is always one binary or decimal sequence that does differs from every other one at a finite digit (hence it is completely irrelevant with respect to this fact, whether or not the differing sequence is infinite, i.e., whether or not it has a last digit). > > But Cantor also proved that for any list of infinite binary sequence > there is an infinite binary sequence not included in it.
Since everything happens in a finite initial segment, there is no reason to consider the question whether the number is finite or has been written with red ink or other irrelevant stuff.
