Roman Numerals

 * $\mathrm L$

The Roman numeral for $50$.

Note
The usual notation for the set of linear transformations involves use of the mathscript font, that is: $\mathscr L$, whose $\LaTeX$ code is, but this does not render in many versions of $\LaTeX$.

Since this site migrated to MathJax, it has become possible to use the $\mathscr L$. However, this has not yet been imnplemented.
