comment Function for number patterns
@nzifnab: I've modified my (incorrect) answer. Since it is wildly incorrect, I think it should be deleted. But I can't delete it since you've accepted it as most helpful. I suggest either: 1) unaccepting my answer and accepting the other answer since it is correct (I favor this one) or 2) if you really want me to keep my answer around because it was helpful, please comment as to that effect (but still you should probably switch acceptance to the other correct answer).

comment Function for number patterns
Do you want the function itself or how to figure out how to get the function if, say the rules change a little?

The second paragraph is the most relevant...I really don't know how to evaluate its last line though: "This famous result is normally misunderstood and Hilbert may not have thought it though at the time". How -is- it supposed to be understood, and in what way was it misunderstood, and which way did Hilbert think of it? I thought it was a statement that labels for types are arbitrary and that the axioms provide the meaning. Is that the misunderstanding?

Exec summary: not really an urban legend, only a tiny bit of hearsay but Hilbert didn't state it intentionally in his published works. Thanks so much all for all the scholarship, amazing (yes, probably just a google search, but it doing it is something)...my next question will be 'who invented the variable?'.

Excellent answer..thanks for the scholarship. I imagined it would have been in Reid's but it looks like all she does is -use- that phrase rather than ascribing any kind of quote. With respect to your addenda, are you trying to say that Blumenthal was most likely not making it up himself but reporting what he thought Hilbert had said?

Excellent...is the Grattan-Guinness mention on-line?

Excellent find...the letter is dated Dec 1899. Of course, none of this was published (and so generally accepted as from Hilbert until the 30's)

@Theo: It could be pronounced differently, the ordinal for 101 and that for k+1.

comment Combinatorial proof
@Adi: Can you modify your question then? (there is a combinatorial interpretation of the derivative, but it may not be appropriate here because the question is not the usual way of interpreting $e^x$ combinatorially)

comment Difference between bijection and isomorphism?
I'm not following a lot of this...forgetting categories and algebraic structures, isn't an isomorphism between two (unstructured) sets a bijection? And if you are trying to preserve functional relationships, then you're talking about a homomorphism? Isn't -that- the level of terminology the OP is asking about?
