"Hurley 2016, pp. 323–252" is invalid. Paprika72 (talk) 10:35, 11 September 2026 (UTC)Reply

What do you mean it's "invalid"? The Hurley 2016 book is cited, and the book has 456 pages according to Google Books. Do you mean that you've read those pages and they don't support the statement they're used for in this article? MartinPoulter (talk) 10:54, 11 September 2026 (UTC)Reply

It's a typo: the second number is smaller than the first one. I fixed it. The passage says rules of replacement ... to express these rules, a new symbol, called a double colon (::), is used and lists several examples. Phlsph7 (talk) 11:11, 11 September 2026 (UTC)Reply

D'oh! I didn't notice that. Thanks for fixing! MartinPoulter (talk) 12:40, 11 September 2026 (UTC)Reply
