Actually, none.

Why? Because no number is "created" this way which wasn't already there.

Hint: {2n : n e IN} c IN and 2ω = ω.

Hence {2, 4, 6, ... 2ω} = {2n : n e {1, 2, 3, 4, 5, ... ω} c {1, 2, 3,
4, 5, ... ω}, where {1, 2, 3, 4, 5, ... ω} = {1, 2, 3, 4, 5, ...} u {ω}
= IN u {ω} and {2, 4, 6, ... 2ω} = {2, 4, 6, ...} u {2ω} = {2n : n e IN}
u {2ω}.

Could you explain how your 'unnatural number' system works?

If all doubled natural numbers remain smaller than ω, then the infinite
space between ω and 2ω remains empty. If the doubling creates these
numbers ω+2, ω+4, ω+6, ..., then they are no longer natural numbers.
What is going on?

No, not nonsense, Mückenheim.

Cantor said 2ω is ω + ω =/= ω.

He only said that in the early years of set theory, later he corrected
himself:

Anmerkung von Zermelo [3] Zu S. 195. Hier und im folgenden stellt
Cantor den Multiplikator voran und schreibt 2ω für ω + ω; in der
späteren systematischen Darstellung III 9 stellt er umgekehrt den
Multiplikandus voran und schreibt ω2, was aus Gründen der Analogie
entschieden vorzuziehen ist, weil auch bei der Addition nur der zweite
Summand (der Addendus), wenn er endlich ist, die transfinite Summe
modifiziert, vergrößert. Vgl. S. 302, 322.

Cantor 1884: Ich habe in den "Grundlagen" den Multiplikator links, den
Multiplikandus rechts geschrieben; es hat sich mir aber gezeigt, daß
der entgegengesetzte Gebrauch, den Multipikandus links zuerst und dann
rechts den Multiplikator zu schreiben, für die weitere Entwicklung der
transfiniten Ordnungszahlenlehre der zweckmäßigere, ja fast
unentbehrliche ist; aus diesem Grunde kehre ich also die betreffende
Schreibweise der "Grundlagen", soweit sie sich auf Produkte bezieht,
von jetzt ab immer um.

Wie dumm kann man eigentlich sein, Mückenheim?

Also nochmal, vielleicht verstehst Du es ja jetzt besser:

| No number is "created" this way which wasn't already there.
|
| Hint: {2n : n e IN} c IN and 2ω = ω.
|
| Hence {2, 4, 6, ... 2ω} = {2n : n e {1, 2, 3, 4, 5, ... ω} c {1, 2, 3,
4, 5, ... ω}.

If all doubled natural numbers remain smaller than ω,

which they do (hint: An e IN: n < ω and hence An e IN: 2n < ω since An e
IN: 2n e IN)

then the infinite space between ω and 2ω

There is no "infinite space between ω and 2ω" since ω = 2ω.

It seems that you are mixing up 2ω with ω2.

If the doubling creates these numbers ω+2, ω+4, ω+6, ...,

It doesn't.

1. "doubling" is not counting

2. doubling the (infinitely many) natural numbers 1, 2, 3, ... results

number ω with 2 from right results in the (single) ordinal sumber ω2.
(Hint: 2ω =/= ω2.)

4. Hence {2x : x e {1, 2, 3, 4, ... ω}} = {2x : x e {1, 2, 3, 4, ...} u

u {ω}} = {2, 4, 6, 8, ...} u {ω2} = {2, 4, 6, 8, ... w2}.

5. ω+2, ω+4, ω+6, ... !e {2, 4, 6, 8, ... ω} and ω+2, ω+4, ω+6, ... !e {2, 4, 6, 8, ... ω2} since (a) for all n e {1, 2, 3, 4, ...}: n < ω < ω2
and hence for all n e {2, 4, 6, 8, ...}: n < ω < ω2 and (b) ω, ω2 !e { ω+2, ω+4, ω+6, ...}. (Hint: ω < ω+1, ω+2, ω+3, ω+4, ... < ω + ω = ω2.)

6. Geht's noch dümmer, Mückenheim?

It is not erroneous but simply a matter of another definition.

They are the second, fourth, and sixth transfinite ordinals.

Not quite. I mean, usually we would say

| ω is the first, ω+1 is the second, ω+2 is the third ... transfinite ordinal

Of course, using the ordinals themselves you might state

| ω is the 0-th, ω+1 is the 1-th, ω+2 is the 2-th ... transfinite ordinal

On the other hand: "Did he win the 0-th prize?" Who would say that?

Using non-standard definitions does not help your case, Mückenheim.

So let's stick to the usual definitions when using set theoretic notions

Sure, I do.

Some of them, yes.

Hint: 1, 2, 3, 4 -- * 2 --> 2, 4, 6, 8

Got it?! 2 and 4 were "already there" before doubling.

Now 2IN = {2n : n e IN} c IN.

Nein, nicht "many", Mückenheim, sondern genau _eine_ Zahl. nämlich ω2 = ω+ω.

You do not accept that doubling of 1, 2, 3, ... ω doubles all structures?

The interval [3, 7] of length 4 becomes the interval [6, 14] of length 8.

I do not accept your claim but accept mathematics: The interval between
ℕ and ω is not longer than a natural number k. Hence the doubled
interval is not longer than 2k. Hence almost all of the infinitely many
ordinal places ω+1, ω+2, ω+3 between ω and ω+ω must be occupied by numbers n + n, where n ∈ ℕ.

We could also use less than 1. But the estimation k ∈ ℕ is sufficient.

WM expressed precisely :

these numbers ω+2, ω+4, ω+6, ..., are no natural numbers. What is going on?

They are the second, fourth, and sixth transfinite ordinals.

Not quite. I mean, usually we would say

| ω is the first, ω+1 is the second, ω+2 is the third ... transfinite ordinal

Of course, using the ordinals themselves you might state

| ω is the 0-th, ω+1 is the 1-th, ω+2 is the 2-th ... transfinite ordinal

On the other hand: "Did he win the 0-th prize?" Who would say that?

WM always wins 0-th prize.
