One can prove a bijection between N and Q by proving Q can be well-ordered which it can be. > > > > > > > Only a Fool would Think Otherwise! > > > > > > > > > > You seem to think otherwise.

Any two sets which are well-orderable with unique non-successor and every element a predecessor biject with each other. N is natually such set. Q becomes such a set when properly reordered: Each member of Q is of form m/n, with m an integer, n a natural, and with no common factor greater than 1.
Order them by increasing values of |m|+n and for equal values of |m|+n by increasing values of m.
This is a well-ordering of Q with a first rational, 0/1, and for each rational a unique successor rational, and none left out.
Thus each rational is now enumerated by the natural number marking its position in that well-ordering, and Mueckenheim is proved wrong AGAIN!.

The normal well-ordeing of N provides them.
