Hello, I noticed the links in the footnotes 131 and 132 are broken at https://orgmode.org/manual/Math-formatting-in-HTML-export.html
I suppose the following links may be used instead: 131: http://docs.mathjax.org/en/v2.7-latest/tex.html 132: http://docs.mathjax.org/en/v2.7-latest/tex.html#tex-and-latex-extensions Thanks, YE Emacs : GNU Emacs 28.0.90 (build 1, x86_64-apple-darwin21.1.0, NS appkit-2113.00 Version 12.0.1 (Build 21A559)) of 2021-12-03 Package: Org mode version 9.5.1 (release_9.5.1-11-g96d91b @ /emacs-28.0.90/lisp/org/)
