I'm at a complete loss to see why you think that proves anything.

Anyway, I'm not going to get suckered into this again. I've said my piece.

You are ignoring the bit above the QED again!

Just say which step you disagree with.

At no point am I lost. However after step 1 you're just tacking words
together in an attempt to sound like you know some math. It's not
something that's particularly amenable to refutation, because it's
not coherent enough to mean anything specific.

In standard theory, step (4) is invalid. In standard theory,
it's possible that Chapernowne's constant contains every
finite prefix of pi, yet not contain pi itself, just as it
is possible for a list to contain every finite prefix of pi
and not contain pi itself.

This appears to be another case of Herc's induction schema,
though I can't be sure since I still don't know what the
difference between the angle and square brackets are. It
might also be a case of the schema:

(Ax (x finite -> phi(x))) -> Ax (phi(x))

Of course, these schemata are invalid in standard theory.

Also, strictly speaking, step (1) is invalid as well. It is
theoretically possible (though highly unlikely) that the
Chapernowne's constant _does_ contain infinitely many digits
of pi after all! Note that as of now, about 10^12 digits of
pi are known, approximately one trillion. (Actually, since
Herc is an Aussie, let me hereby use the international term
"billion" instead of "trillion.") And so it's possible that
the second billion digits are equal to the first billion
digits plus 1, the third billion digits are equal to the
first billion digits plus 2, the fourth billion digits are
equal to the first billion digits plus 3, and so on. Then
Chapernowne's constant will contain all the digits of pi,
starting from about the 10^24-th (Aussie "quadrillionth,"
Yankee "septillionth") digit.

This is highly unlikely, but theoretically possible (just as
it's possible, though unlikely, that pi contains only
finitely many digits other than 0 or 1, an oft-mentioned
example of this). As unlikely as its negation may be, it's
still not the sort of thing that should be mentioned in any
formal _proof_.

Notice that the first five digits of pi, "31415," appear
unusually early in Chapernowne's constant:

C_10 = 0.1234567891011121_31415_16...

but we have to go far just to find one more digit, "314159."

But of course, Herc is now a finitist, which means that he
doesn't work in ZFC at all. In a theory in which every set
is finite, the schema:

(Ax (x finite -> phi(x))) -> Ax (phi(x))

trivially holds. But Herc wanted to know with which step
someone like Else (who does work in ZFC or some other
standard theory) would disagree with, and so I answer.

Step 2 then?

>> 2/ as the length of C10 digit expansion -> oo, the consecutive number of digits of pi -> oo


Seems trivial to me.
