Hello, I'm Elizium23. I noticed that you made a change to an article, List of Christians in science and technology, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

"29 is the smallest positive whole number that cannot be made from the numbers {1, 2, 3, 4}, using each exactly once and using only addition, subtraction, multiplication, and division.[7]"
I can see how to get all positive integers between 1 and 25 inclusive (and also 30, 32, and 36), but not 26, 27, 28, 29, 31, 33, 34, 35, or any larger number. So I don't see how 29 can be the smallest positive integer that cannot be formed this way; that would seem to be 26. Also, it is not at all obvious that Ref. [7] is at all relevant, since I don't see that it discusses anything similar. Donpage (talk) 03:50, 2 September 2023 (UTC)


 * Oops, I now see how to get 26, 27, and 28, so it seems that 29 may indeed be the smallest whole number that cannot be gotten this way. However, I still don't see how Ref.[7] shows this or is relevant to this claim.  Perhaps I am also just overlooking something here, but I would like to see a more transparent reference to this claim about 29. Donpage (talk) 21:15, 5 September 2023 (UTC)
