A potentially infinite sequence has *not* more elements than every
natural number. There are only, if we may apply this terminus,
countably many such sequences. A list of them can be complete (in set
theory, not in reality). If a complete list of them yields a digonal
that is not in the list, then the self contradictory character of the
diagonal argument is obvious.
