I got it wrong. It is not multiplying or raising the dimension that
changes the size/order of an infinitive set. It is raising it by itself.
E.g. multiplying the number of real numbers on a line by itself,
itself's times. (Badly explained but I'm sure you can work out what I mean.)
I had a really bad journey yesterday, sitting on a grounded plane at the
wrong airport for four hours. So I am not going to hurt my brain any
more by reading about the perverted going ons of trans-infinities.
(If fractions were good enough for Alfred E Neuman then 11 dimensions,
or is that 10, are good enough for me. :-) )
