is Dedekind-infinte:
the successor function is a bijection between the set of all natural
numbers and non-zero natural numbers.
This "bijection" appears possible but it is not.
So you say that there is a natural number that does not have a next
natural number. What number is that?
We cannot name dark numbers as individuals.
Shame.
All numbers which can be
used a individuals belong to a potentially infinite collection ℕ_def.
There is no firm end. When n belongs to ℕ_def, then also n+1 and 2n and
n^n^n belong to ℕ_def.
And thus all n e N do.

The only common property is that all the numbers
belong to a finite set and have an infinite set of dark successors.
If all successors belong to N_def, it can’t be finite and the
successors can’t be dark.

This is the only way to explain that the intersection of endegments
E(1), E(1)∩E(2), E(1)∩E(2)∩E(3), ...
loses all content in a sequences which allow the loss of only one number
per step.
The explanation is that the sequence is infinitely long.

It is not guaranteed that n+1 exists for every n.
