In your special case we can get away with the built-in \triangledown to represent the lines connecting each vertex. We can also make use of \odot to represent each ringed node: $$\begin{array}{ccc}\hline\text{Case}&\text{Coxeter diagram}&\text{Vertex configuration}\\\hline\text{1 ringed node}&{}^{\boldsymbol p}\hspace{-0.15cm}{\Huge\triangledown}... 11 The \substack command allows one to stack several lines under (and over) an operator symbol like \sum, \prod etc. The argument is enclosed in braces, and lines are separated by a double backslash. For example \sum_{\substack{k = 1 \\ k \neq \lfloor n/2\rfloor}}^{n} x_k produces$$\sum_{\substack{k = 1 \\ k \neq \lfloor n/2\rfloor}}^{n} x_k$$where two ... 7 Your proposed title is Showing \frac{|\overrightarrow{A_1B}|}{|\overrightarrow{A_1C}|}\frac{|\overrightarrow{B_1C}|}{|\overrightarrow{B_1A}|}\frac{|\overrightarrow{C_1A}|}{|\overrightarrow{C_1B}|}=1 implies AA_1, BB_1, CC_1 concur (215 characters). Since \newcommand is now local, I believe it is safe to do [Edit: as per Martin's comment, this may ... 6 Try TeXForm[] in Mathematica. TeXForm[Integrate[f(x), {x,-7,\[Pi]}]] which outputs \int_{-7}^{\pi } f(x) \, dx Putting that between dollar signs on this page \int_{-7}^{\pi } f(x) \, dx yields \int_{-7}^{\pi } f(x) \, dx. (footnote 1) Between double dollar signs,$$\int_{-7}^{\pi } f(x) \, dx \text{.}  It's not perfect, and you may want to tweak ...
