No. We have a "limit" (not an infinite limit however) of the list and
of the FIS of the d (which both are the same) that assumes a natural
number which however cannot be known.

The "limit" is a variable, yes.

Exactly!

Wo does that? Note, there is no "set |N" in potential infinity. The
"set |N" is an actual, i.e., completed infinity. But this assumption
is contradicted (see below).

But one can use such arguing without being considered as such?
Remember: Your point of view requires, what you often have emphasized:
There are all FIS of d in the list, but there is no line containing
them. This implies that they are distributed among several lines and
contradicts the plain fact, according to which the list is
constructed.

Do you have any explanation for that point of view?
