Olcott is trying to stay at this point for several weeks now, but he does not succeed. The reason probably is, that it is already a few steps too far. First there must be agreement about the words and terms used in what he says. So, we should delay this subject and go back a few steps.
Before we can talk about this, first there must be 100% agreement about:

It your claim, so you have the burden of a proof. Not knowing a counter example is not a proof. It seems you are using such excuses to hide the fact that you don't know how to prove it. Again, if there is a proof, show it. Otherwise stop saying that it is a verified fact, because it becomes more and more clear that nobody verified it.

is even weaker. If there is a proof, it would be so simple to show it here. As even olcott said that a verified fact is a proven fact, he cannot speak of a verified fact as long as there is no proof. I have 50 years of experience in programming, many years in C, so I am a very skilled C programmer. So, why do you hide the proof? I wonder what the next excuse will be to hide the fact that there is no proof.

Further, it seems to be another indication that olcott does not understand how a proof in computation theory looks like. It is not like a juridical proof, where the number and expertise of witnesses play a role.
In computation theory a proof consists of a number of steps, starting with the definitions of the elements involved and of the axioms of the theory, resulting in a conclusion. Each of these steps can be explained from the definitions, axioms and results of previous steps.
Olcott, again, if you want to convince people, learn how to formulate a proof. Up to now, we have not seen more than your conviction, without evidence. Present the proof and we will see whether we understand it.

Olcott is claiming, so olcott has the burden of the proof. Without a proof, it is not "verified fact", but "my belief".
(a) olcott knows that there is no such proof.
(b) olcott has no idea how to formulate a proof.
(c) olcott thinks he has a proof, but does not dare to show it, because he is afraid that someone will spot an error in it.

Again no proof. Now the excuse is that it is self-evidently true. A bad excuse, because it is self-evident only for olcott. That is what we call belief. It shows again that when olcott writes 'verified fact' we should read 'my belief'. Sorry, olcott, but with only your belief, your are not going to invalidate a proven theorem in computation theory. You will convince nobody if no proof can be supplied.

 Again no proof. But it seems that olcott is slowly starting to understand that it is not self-evident, because he now shows a small beginning of an attempt for a proof. It is a pity for him that he ignored the rest of my post where I told him a brief outline for a proof.
What we still miss are the requirements for H.

I try to do the best that I can to write my words so that even people
with attention deficit disorder (ADD) can understand them.
The ONLY requirement for H as I have said many many hundreds of times
is that H simulates D.
The self-evident meaning of what D correctly simulated by H means is
now specified so that people trying as hard as possible to make sure
to find any loophole to intentionally misinterpret my words will look
much more foolish.

A working example is not enough to define an infinite set of H. So, define the requirements.
 

I did and always have. Possibly not well enough for people having
ADD that can hardly pay any attention. Not well enough for people
having insufficient knowledge of the semantics of C.

Then, do not only claim that there is a simulation invariant, but prove it.

Prove that 2 + 3 = 5 to someone that does not know what numbers are.
No need for any proof for people that understand arithmetic.

Of course you need to master a language to express such a proof. If you don't master such a language, try to learn it. Claiming, without evidence, that it is self-evident is not part of the correct language.
 

If you have ADD and can't pay attention or do not know the semantics
of C well enough to understand that I have proved my point I don't
know what I can do to help you understand that what I have said has
always been self-evidently true for everyone having sufficient
knowledge of the semantics of C.
Tell me which part you don't understand and I might be able to help.
If you have no idea what infinite recursion is then I cannot help.

Then explain how H determines that there is a recursive simulation, so that it can abort the simulation.
 

*That is not any part of what I claimed above*
*That is not any part of what I claimed above*
*That is not any part of what I claimed above*
*You must pay 100% complete attention to my exact words*
*You must pay 100% complete attention to my exact words*
*You must pay 100% complete attention to my exact words*
If you don't have that much attention span, I can't help.
If you don't have that much attention span, I can't help.
If you don't have that much attention span, I can't help.
