 | Lest any man or woman to challenge this claim to 1st correctly answer this question.
================================================= How many flips of DIAG are on the infintie list of infinite coin flippers? =================================================
Infinite people each flip coins, some infinite times each, can you always come up with a new sequence of Heads and Tails?
AntiDiag = |<------ How Many flips ? ------->|
Infinite Flippers List 1 2 3 4 5 ....
Its not a hard question, remember John Savard's comment, "a random real number will be on it to an infinite number of digits"
The p0int being lim x->oo in a billion texts is unrelated to cardinality theory and people shouldn't be forced out of using the term.

The claim is Not granted.
oo consists of two symbols not one.
Try again.

Answered elsewhere.

Then if you are talking about cardinality theory, why not use the symbols from that theory when discussing cardinality instead of the ambiguous and unrelated symbol oo?

I seriously doubt that the destiny of the symbol oo will be decided on sci.math.

Any finite subsequence of the antidiagonal of the list appears on the infinite list. The infinite sequence does not, and clearly cannot, as it differs from sequence (n) at position (n). I hope this answers your bizarrely phrased question.
Why not try asking this question, which is equivalent?
Define A = { f:N->{H,T} } (A is the set of all functions from the naturals to the set containing H and T, i.e. the set of all "infinite coin flippers")
Suppose l:N->A is a surjective function (l is the list which attaches a natural number to each "infinite coin flipper" sequence, you call it the "infinite flippers list")
Define g:N->{H,T} as follows - g(n)=(l(n))(n). This is the diagonal of l. (l(n) is the nth "infinite coin flipper", so (l(n))(n) is the nth position in the nth infinite coin flipper)
Define h:N->{H,T} by h(n)=H when g(n)=T and h(n)=T when g(n)=H (h is the antidiagonal).
This is a much easier way to view the problem, rather than looking at the functions as sequences of digits. Clearly h should be a member of A, because it's a function from N to {H,T}, but it isn't, because it differs from every member of A. This is a clear contradiction, so we must conclude that no function l exists, and therefore N and A are not bijective and don't have the same cardinality.
Is this what you're driving at?

The oo in lim(x->oo) doesn't literally mean "as x goes to infinity", it has very particular meaning involving certain conditions that are fulfilled for large x. Infinity doesn't really have anything to do with it; it's merely a convention.

So how many flips of DIAG are in any finite subsequence of DIAG?

 | I once did an experiment to see how many 'coin flips', 0 or 1 binary, it would take to reproduce a 32 bit binary number.
On the first attempt you had 50% change of being correct, the 1st and the second both being right was 25%, etc.
It turns out about 32 bits of tries was needed to randomly find the sequence.
This was an attempt at data compression, which was fun, but by itself not useful (or not useful at all perhaps)
