> I plan to correct these moments and of course, leave links to the original functions and systems of ordinal notations.

Good to hear that. I note that there are few (no?) articles in this wiki explaining an existing ordinal notation, and hence it is good to refer to the original papers when you study by yourself.

For example, Buchholz's ordinal notation does not employ Buchholz's \(\psi\), and Rathjen's standard ordinal notation based on weakly Mahlo cardinal is an array notation, in which there is no occurrence of Rathjen's \(\psi\), either. Therefore they are not what many googologists here imagine from "descriptions" in blog posts written by others, who also "learned" ordinal notations from other blop posts. Misunderstandings are spread in this way. Learning from the first source is very important.
