Sufficiently more that 2lines, namely infinitely many, will contain far more than any one line. > > > >> In mathematics this principle never fails. It is too obvious. > > You just said it failed.

In WM's wild weird world of WMytheology actually infinite sets simply may not exist, but they do outside of it. >

It is already there as any one column of this matrix: 1 2 1 3 2 1 . . .
or any one diagonal of this matrix: 1 1 2 1 2 3 . . .
or even as a row of this matrix: 1 2 3 ... 1 2 ... 1 ... ...

Only if there are also an actually nfinite number of rows.
It there is a last row and last column, there is only space for a finite number of positions.
To get an actually infinite number of positions one must have at least an actually infinite number of rows or an actually infinite number of columns.
But in WM's world, where there are no actually infinite anythings, his diagram is a lie from the start, as it cannot exist in his world.
But it can in ours,
