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.

 – Nothing personal in this discussion

Hi, thanks for catching that error in my edit to the intro to "Determinant." I think the introduction is still a bit inadequate, and started the relevant discussion on the talk page. Cooljeff3000 (talk) 12:16, 2 July 2024 (UTC)[reply]

I disagree with your reversion of my edit. This is the introductory article that people see when you look up basic facts about functions. I checked the article, and nowhere is the meaning of the \mapsto symbol defined. It may not have to be defined in the way I did, but it should be somewhere in the article. You should make additional changes to it if you're not satisfied with how it's introduced, but for now, I am reverting your reversion. Alsosaid1987 (talk) 00:06, 15 July 2024 (UTC)[reply]

Normally, this sort of discussion must be on the talk page of the article. This allows the watchers of the article to know of it and to give their opinion in view of a consensus.

Nevertheless, you say that \mapsto is not defined in the article. IMO, it is perfectly defined by: A function f, its domain X, and its codomain Y are often specified by the notation ${\displaystyle f:X\to Y.}$ In this case, one may write ${\displaystyle x\mapsto y}$ instead of ${\displaystyle y=f(x)}$.
