563:...and when a derivation is so simple that any high-school student can check it in a minute, does that come under the OR rule? I think there's been some discussion of this before. If I multiply 777 by 286 and report that I got 222,222, and it happens by some freak chance that no one has ever multiplied that exact pair of numbers before, am I violating the OR rule? If so, lots of articles are in trouble.

not particularly notable article or publication is definitely not enough. But that's all we have with the references in the article so far. Moreover none of the involved here has actually seen any of the discussed sources first hand, so strictly speaking we couldn't even exclude a smart fake for sure.--

The 2 references in the article are not good enough (as pointed out in the original AfD) and the 2 books found via google books might be good enough,

The problem here is not the mathematical correctness but the notability of the term "clarkson sacroll formula". A redirect makes only sense if the term is actually mentioned in the target article and if there's sufficient evidence that the term is established/used/somewhat known. The current sources

Imho the former case alone might not be good enough and currently we don't really have reliable evidence for that. I don't think a widespread use is necessarily required, but i'd say some use within a community is required and somebody not particularly notable calling it (once) by that name in some

If there's something reasonably called a "scroll formula" and it's clearly due to someone named
Clackson, is that enough reason why an article about it should be called "Clackson's scroll formula" or "Clackson scroll formula" (presumably preceded by the definite article when used in a sentence), or
959:
But how do we know that this equation is properly known as the "clackson scroll formula"? Maybe its properly called something else? My point is that we have nothing more than original research right now, that we can confirm is mathematically correct. How do we even know that it's notable or even

can be found in that article (until this estimate was added). I'd have guessed an exact formula would appear (whether "closed-form" or not I won't guess right now). That a simple estimate originated out of a need arising in a field other than pure geometry is interesting.
214:
Per the talk page, one source is a primary source and the other is non-reputable, therefore notability is not asserted. Moreover, a detailed interest search doesn't show any such equation or principal, therefore I think this is a made-up concept.

I don't think that's a good idea, because, as far as I can tell, the equation is made up. So unless you can find a real confirmable reference, I think you are propagating a fallacy.
