    What if countability is inconsistent? The following is adopted from Mueckenheim:
    If the fractions m/n are enumerated by the natural numbers k according to Cantor's function
    k = (m + n - 1)(m + n - 2)/2 + m
    then all the fractions of the sequence
    1/1, 1/2, 2/1, 1/3, 2/2, 3/1, 1/4, 2/3, 3/2, 4/1, 1/5, ...
    are enumerated.
    But if the natural numbers first are in bijection with the integer fractions of the first column of the matrix
    1/1, 1/2, 1/3, 1/4, ...
    2/1, 2/2, 2/3, 2/4, ...
    3/1, 3/2, 3/3, 3/4, ...
    4/1, 4/2, 4/3, 4/4, ...
    5/1, 5/2, 5/3, 5/4, ...
    ...
    then they must be distributed over the matrix such that no fraction remains without index. That means, there is a permutation such that the X of the first column
    XOOOO...
    XOOOO...
    XOOOO...
    XOOOO...
    XOOOO...
    ...
    by being exchanged with the O's cover all matrix positions. All O's will vanish. This is obviously impossible because exchanging cannot reduce them. The number of not indexed fractions, represented by O's, will remain constant forever, in infinity.
