...You can say that finite sets have their own individual
cardinalities if you want (number of elements), but I have found it
easier if you treat the finite sets as one class, the r.e. sets as the
second, the reals/subsets as the 3rd., etc.
Finite sets are r.e. Does this mean your first class is included in
your second class? Also, where do denumerable non-r.e. sets fit into
your picture? (NB: For mathematicians, "denumerable" = "has cardinality
aleph_0", so you'll need to be careful when you frame your answer, given
that, in your unique idiolect, "aleph_0" = "finite".)
