I answered that already. If you define 'the width', then it turns out
to be equal to omega, which is just what the length of the diagonal is.

The diagonal is assumed to exist such that each of its digits exists,
actually. This is established by the mapping on a column. But it cannot
be established by the mapping on any line.

Why should the diagonal have to be mapped onto one line when it is not
constructed from one line?

WM seem to have all sorts of peculiar requirements for things that need
not be required for anything except his own squirrelly views of things.





I answered that already. And the cardinality of the diagonal is not
assumed, but is proven, to be omega.

It is *assumed* by stating the axiom of infinity. Without this
assumption the length was not omega.

The axiom of infinity has not been shown to cause any problems within ZF
or NBG, and WM has not produced any /system/ in which it does not hold.
