I am not interested in sufficient sets but in necessary sets.

each of which contains only unnecessary lines. At least hitherto
nobody has succeeded in naming a necessary line. Every named needed
set starts with a not needed number.

then the intersection of them is empty.
How can they all contain the complete set of natural numbers in this
And if at least two of these sets contain |N, how can they be

What is eoither? Here my dictionary fails.

What is the first one?
I can prove by induction, that there is no necessary subsequent line,
except a / the last one.

It is a pity. You and your ilk are unable to apply induction, but
boast of of "transfinite induction". Note: Transfinite induction can
be applied to show that its applyer is a fool that should be inside a
mad-house. Further merits of transfinite induction are not known.
