Almost seems like: making indices N x N, has that for the one image,
each element is finite yet unbounded, while for the other it is
infinite. This basically gets into considering a copy or instance of
N, then another, has in some manner the sputnik of quantification or
here correlation among the two, that for the same specification, one
has finite and unbounded elements, the other finite and unbounded and
as well: infinite elements.
Basically that an omega-sequence is constructed, here with the n-
sequence of unary digits being a natural integer, the omega-sequence
is in N where: the complement of the correlate/diagonal is an element
of the language of 1*, that the language admits infinite elements when
there are the two copies or instances of N, where in N by itself,
that's just the successor.
Why would this be? It seems simple to talk about as many copies of N
as as convenient to model free variables of unbounded automata, but
one might consider that these still come from some reserve of
distinguishable elements, of all of them. Then to have that two
copies of N so correlated/scaffolded see the admission of infinite
elements, that could only be from the language 1*, where with one or
more copies not so correlated there are only finite if unbounded
elements, might be seen as a development along the lines of the
Russell element of the Russell set as sputnik of quantification (of
regular sets), the omega-sequence of sputnik of correlation (of free
natural variables).
