What do you mean by 'dense at a point'? Do you mean dense within an
upper and lower bound?
Density is per an ordering. The rationals in [0 1] are dense with the
standard linear ordering of the rationals, and there is a bijection f
between omega and the set of rationals in [0 1]. Let R be the ordering
of omega as: Rnk iff f(n) < f(k), where '<' stands for the standard
linear ordering of the rationals. Unless I'm mistaken, that provides
that the set of natural numbers is dense and bounded with the ordering
R.
