All of classical mathematics is embedded into potential infinity.

I am interested in actual infinity. We cannot prove its existence but only 
apply logic like this: If a complete chain exists which does not continue 
into the negative, then it ends before. Either at one or at more members. 
The latter is excluded by ∀n ∈ ℕ: 1/n - 1/(n+1) > 0 .

Of course. After each one there will appear more. Choose the smallest one 
you can, recognize that there are many more following.

There is no set ℕᵈᵉᶠ because of lacking completeness. Sets of set 
theory are complete.
