It is lines, not naturals, that are the members of such sets.

But it does satisfy the rule that every set of lines that covers all of

|N has a first line and also satifies that no such set of lines has a

last line..

Which one? There are infinitely many such sets, each having both a first

line and for each line a next line.

In fact every set of lines that covers all of |N has both a first line

and for each of its lines a next line.

And every set of lines that fails to include all of |N must either not

have a first line or must have some line for which there is no next line.

====================================================================

WM claims to know how to map bijectively the set of infinite binary

sequences, B, linearly to the set of reals and then map that image set

of reals linearly ONTO the set of all paths, P, of a Complete Infinite

Binary Tree.

But each binary rational in |R is necessarily the image of two sequences

in B but that one rational can then only produce one image in P, so the

mapping cannot be the bijection WM claims.

SO that WM is, as usual with things mathematical, wrong.
