Hello :D

I'm trying to write a statement for a problem using Polygon, but there are so many things that should be easy in LaTex but yet are "unsupported" in polygon. Is there any documentation for what subset of LaTeX is available in Polygon for HTML statements?

Here is some of what I frequently need but polygon rejects, if you can help with the 'Polygonic' way to perform this, it would be awesome :D

• Insert a newline or a linebreak: tried both '\\' and '\newline'.
• A horizontal line: tried '\hbreak'
• A table: tried both '\begin{tablular}' and '\begin{table}'
• A matrix: tried '\begin{matrix}' and '\begin{array}'

So yeah, without a documentation on supported LaTeX commands, I get stuck way too often trying to find alternative solutions. Is there any help?

Also, is there a way to check the LaTeX code behind already existing problems? It would be much much easier to just find what I want and copy the format.
