You and your HHH can reason or at least conclude correctly about
Infinite_Loop but not about DDD. Possibly because it prefers to
say "no", which is correct about Infinte_loop but not about DDD.

You are the lying one.

No, we don't. There is no such prohibition.

Turing machines never take actual Turing machines as inputs.
They only take finite strings as inputs and an actual executing
Turing machine is not itself a finite string.
The definition of a Turing machine does not say that a Turing machine
is not a finite string. It is an abstract mathematical object without
a specification of its exact nature. It could be a set or a finite
string. Its exact nature is not relevant to the theory of computation,
which only cares about certain properties of Turing machines.
>Therefore It is not allowed to report on its own behavior.>
Anyway, that does not follow. The theory of Turing machines does not
prohibit anything.

machine and thus accurately report on its actual behavior.
If a Turing machine can take a description of a TM as its input
or as a part of its input it can also take its own description.
Every Turing machine can be given its own description as input
but a Turing machine may interprete it as something else.

It is empirically proven that this changes their behavior
and the behavior of DDD.

The x86 code is exactly the same, therefore, the semantics of the x86 does not change, which proves that your claim that HHH works according to the semantics of the x86 language is not true.
This is your last chance before I ignore everything you say.What is the problem? Are you unable to understand what I say, or are you unwilling to understand what I say?
int main()There was no infinite recursion, because HHH aborts after two cycles.

HHH1(DDD);
