I would like to use a symbol in a chemical reaction equation which represents a solid's surface.
A common symbol used for this purpose is '>' or the
\equiv symbol, but what I would like is actually something like the
\equiv symbol but with the length of em-dash (basically like 3 em-dashes stacked on-top of one another).
Ultimately though, I would actually like a symbol with 5 lines on-top of each other, the height of a normal capitalized character.
Do you guys know of any such symbol that may exist? Or, is it possible to 'build' something like this?
