Hi Markus, it's not exactly a subset of LaTeX. Some commands were added some were removed. A large portion of those parts are documented here https://en.wikipedia.org/wiki/Help:Displaying_a_formula , and a complete list is available from http://1drv.ms/1RtoZoW For LaTeX users I created a LaTeX macro package so that they can copy and paste texvc style LaTeX code to regular LaTeX documents https://www.ctan.org/pkg/texvc However, there are two issues with this package: \and and \or are not supported by my LaTeX package since redefining those commands caused internal problems. However, most of the time people use the standard LaTeX command \lor and \land anyhow. Altogether, enwiki contains 969 \lor and 1581 \land. Statistics on the usage frequencies are available from https://gitlab.tubit.tu-berlin.de/data/wikiFormulae/tree/master
w.r.t 2) I have no idea how that relates to MathJax? Can you explain the background of your question? Best Moritz Moritz Schubotz TU Berlin, Fakultät IV DIMA - Sekr.

(2) As a follow up: does MathJAX work to display this? If not, what does?
