Safe Primes, in RSA

Ok, let's try to discuss here: https://en.wikipedia.org/wiki/Talk:RSA_(cryptosystem)#Safe_Primes,_in_RSA_Key_Generation No "reliable sources" are needed here. Here you just need to think with your own head. This is math. In any case, I do not owe you anything, and I do not demand anything from you.

Higher-order derivatives link in derivative article

Summarize

Perspective

Hi @D.Lazard, you cited WP:NOTBROKEN as the reason for your revert of my section link change. I made the change because the existing link only goes to the top of the derivative article and not to the Higher-order derivatives section; so the existing wikilink is an incorrect navigation. I'm not one for edit wars, so I won't make a further edit on the article, but you may want to improve the article yourself. Duncnbiscuit (talk) 02:35, 11 October 2025 (UTC)

I do not understand: for me Higher order derivative, higher order derivative, Higher-order derivative, and higher-order derivative link all to Derivative#Higher-order derivatives. Note that if you want the plural, the final "s" must be after "]]". Maybe, the target is not correctly displayed when hovering over a preview. But this does not mean that the published version is incorrect. D.Lazard (talk) 08:36, 11 October 2025 (UTC)

it might be that I mostly access Wikipedia via the Android app, which may well have different behaviour to the Web or IOS versions of Wikipedia. Duncnbiscuit (talk) 08:55, 11 October 2025 (UTC)

This may also depend whether you access to Wikipedia through the application or through the web site with your browser. (reading your post again, this is almost what you said.) D.Lazard (talk) 09:40, 11 October 2025 (UTC)

Contact

Hey @D.Lazard, it has been a long time since we've interacted, but I have a matter I hope to chat with you about on the subject of commutative rings. How can I get in contact with you? I tried a @lip6.fr email from a not-too-old paper but it bounced :(

Anyhow, glad to still see you around on WP, and I hope we get a chance to talk more. Rschwieb (talk) 03:40, 14 November 2025 (UTC)

Glad to see you again here.

I do not like to publish my e-mail address on the web. So, the best is to use the WP- option "e-mail to this user" to start a private exchange.

Sincerely, D.Lazard (talk) 09:16, 14 November 2025 (UTC)
