# Drawing Coxeter graphs including arrows

In his paper "Reflection centralizers in Coxeter groups" Allcock included (in Section 4) Coxeter graphs of the form below. I would also like to draw graphs like this in my Latex document but I do not know what package to use (and how to do that). (Usually you can download the .tex file from the paper on arxiv but somehow I didn't manage to do that.)

Has somebody a good suggestion?

• Do you need the thick curved arrows? – Bernard Sep 17 '20 at 14:42
• Yes, I do also need these. – worldreporter14 Sep 17 '20 at 14:43
• Show us what did you try. – hola Sep 17 '20 at 14:43

The tex source of mentioned paper is available from link https://arxiv.org/e-print/1106.3822v2 on webpage https://arxiv.org/format/1106.3822v2. You may need to append file extension .tex to the downloaded file.
The tex source shows that graph is drawn by pstricks:
The second example is $D_{n\geq6}$, which has $n-1$ arrow classes (starting at line 1401):
