Not in what you know about these sets,
but existing,
because:
⎛ WM: There is no gap.
⎝ JB: Yes
⎛ WM: Two points are next to each other
⎜ means that
⎝ no point is between them.
ℝ[ℚ[ℤ[ℕ[⟨0,…,n⟩]]]] includes ℚ[ℤ[ℕ[⟨0,…,n⟩]]]
No positive distance r > 0 exists such that
an r.length gap exists in ℚ[ℤ[ℕ[⟨0,…,n⟩]]] where
there aren't any q′ ∈ ℚ[ℤ[ℕ[⟨0,…,n⟩]]]
⎛ ¬∃r ∈ ℝ[ℚ[ℤ[ℕ[⟨0,…,n⟩]]]]: 0 < r ∧
⎜ ∃q,q″ ∈ ℚ[ℤ[ℕ[⟨0,…,n⟩]]]: q+r ≤ q″ ∧
⎝ ¬∃q′ ∈ ℚ[ℤ[ℕ[⟨0,…,n⟩]]]: q < q′ < q″
Two points are a distance r > 0 apart.
There is no rational.free gap between them.
There are rationals between them.
The two points are not next to each other.
There are no two points next to each other in
ℝ[ℚ[ℤ[ℕ[⟨0,…,n⟩]]]]
Next to every defined points
there are ℵo dark points.
This configuration cannot be changed.

That's not enough.
There aren't any more,
not if we are discussing a line which
includes all rational points and
includes enough points more such that
functions continuous at each point
don't skip.over anywhere.
That's enough points for physics and
many other "common sense" purposes.
However, although each ⟨0,…,n⟩ is finite,
ℕ[⟨0,…,n⟩], ℤ[ℕ[⟨0,…,n⟩]], ℚ[ℤ[ℕ[⟨0,…,n⟩]]],
and ℝ[ℚ[ℤ[ℕ[⟨0,…,n⟩]]]] are infinite.
Describing ℕ[⟨0,…,n⟩], ℤ[ℕ[⟨0,…,n⟩]],
ℚ[ℤ[ℕ[⟨0,…,n⟩]]], and ℝ[ℚ[ℤ[ℕ[⟨0,…,n⟩]]]]
as finite,
for example, as their having
each nonempty.subset two.ended,
leads to gibberish and
is an incorrect description.
Note, too, that
adding more points can't make them finite.
