of course not.

"Cantor believed the continuum hypothesis to be true and for many years tried in vain to prove it.[3] It became the first on David Hilbert's list of
important open questions that was presented at the International Congress of Mathematicians in the year 1900 in Paris. Axiomatic set theory was at that
point not yet formulated. Kurt Gödel proved in 1940 that the negation of the continuum hypothesis, i.e., the existence of a set with intermediate
cardinality, could not be proved in standard set theory.[2] The second half of the independence of the continuum hypothesis – i.e., unprovability of the
nonexistence of an intermediate-sized set – was proved in 1963 by Paul Cohen.[4]"

That erases the matrix of fractions, and replaces it with O pasties, and X stickies.

Now WM has taken off the X pastie at 1,2 and put an O stickie on it.
And then WM takes off the O pastie at 2,1 and puts a X pastie on it.
there are no swaps here.

Now WM has taken off the X pastie at 1,3 and put an O stickie on it.
And then WM takes off the O pastie at 1,2 and puts a X pastie on it.
there are no swaps here.
just continual replacement of stickers and pasties

Liar, Cantor did not use pasties and stickers.

What did you do with all the O stickers ??
Where did you get all the X and O stickers ?
