Not enumerating all positive rational numbers
... It is easy to see that at least half of all fractions of this sequence belong to the first unit interval (0, 1]. Therefore, while every positive rational number q gets a natural index n in a finite step of this sequence, there remains always a set sn of positive rational numbers less than n which ha ...
