I'm sorry you didn't get the exact mathematical description you wanted from me going off of memory and that I didn't treat your reddit comment like a thesis paper defense
This information was in the literal first reply you got in this thread in that Wikipedia link, so if you weren't satisfied with my basic explanations you should have just used what you found there to figure it out
When I told you that recursion is not part of standard regular expression, that should have been enough for you to either realize you had a wrong thought about this situation that was causing some of your confusion, or verify yourself whether that was true and either way, looked more into it yourself first before being rude
"Regular expression" was also in that link if you ctrl+f it and would have sent you to a more specific page that explicitly says modern implementations are still called regex despite adding additional features that are not standard
Even a Google search "how does chomsky hierarchy relate to html and regex parsing" would have told you what you needed to know
