Oh, BULL.
Practically every respondent ALWAYS TELLS YOU EXACTLY
where your gaps are! I know I do. In a message you are not replying
to, I told you that the gap was that you had not defined A or f_A and
that
THAT was EXACTLY where your gap was. But I don't see you bothering to
try to fill it.

WHy are you even trying to disagree with Cantor's theorem in the first
place??
Does it not occur to you that since there are proofs of it in books,
IT OBVIOUSLY
MUST be right?? Why don't you instead point to some SINGLE SIMPLE
INDIVIDUAL
piece of the proof that you don't understand, and offer a simple
counter-
argument TO THAT? IF you "aced propositional logic" then that
shouldn't
be hard.

what is obvious to you is not
necessarily obvious to me.

Yes it is, actually. "Obvious" is just like that.
It ReallY IS OBVious.

I've given it some thought and frankly
cannot come up with a sensible solution other than asking others where
I am deficient.

Here is one: READ A BOOK.
Do you really need someone to recommed you a book?!?

I tried asking for a "logic buddy",

That will also work. I am qualified.
But you have to be able to admit that you are messing up.
Most people have too much undeserved ego to use me.

someone who can
convert ideas into mathematical notation,

idiot: THAT is NOT a logic buddy!
Logic does not give a HOOT about "mathematical notation"!
Neither do you, as long as you are going to keep writing (Ex)
(whatever).
THAT IS STUPID notation! As Arturo OUGHT to have figured out by now,
from
the trouble it has put you into.

but no one is interested.

That is NOT at all true.
EVERYbody wants SOMEbody to feel superior to.

I have tried going through some of the problems in the books I have (for
those which have solutions) and I am getting them right.

Nobody here believes that, ESPECIALLY if you are stupid enough to be
asking questions like "how do you prove a subset does not exist" and
denying the axiom of separation and expecting to find some flaw in
a proof of Cantor's theorem. THIS IS NOT NORMAL behavior,
ESPECIALLY
not normal for people who are actually SHOULD be "doing" logic.

So outside of
picking something challenging and asking for others to point out
deficiencies, I am at a lost for how to find those gaps.

Clue: SIT DOWN, SHUT UP, and remember that if God had wanted you to
talk
more than you listen, he would've given you 1 ear AND TWO MOUTHS.
EVERY time you post something stupid, people TELL YOU TO STOP
doing it that way and TELL YOU TO START doing it this way:
JUST OBEY THEM.
It Really Is Just That Simple.
You basically will have to be A SLAVE BEFORE you can be a student.
If that bothers you then yes, you definitely will STAY ignorant.

If you can
think of an alternate, I'm all for it.

I told you 5 times already to STOP writing (Ex)(whatever) and START
writing
Ex[cond(x)]. THAT'S One alternative, one you have THUS far been NOT
all for.
IF you would start doing that then it would become possible to explain
to you
WHAT A WFF IS.

Something that you somehow managed to miss in all your books is that
0) propositional logic is also called 0th-order logic;
1) if you pretend that conjunctions and disjunctions can be infinitely
long, and
you grant yourself the ability to state conjunctions or disjunctions
having 1 conjunct
for each thing IN A DOMAIN of discourse, then you are doing something
called 1st-
order logic, which is BASED on the concept of a 1st-order LANGUAGE.

Once you understand the grammar for 1st-order languages, it will
become
possible for you to stop writing nonsense. Until then, there is
simply no (other) point.
THAT is where your gap is.
