I'm pretty sure the E6 diagram is wrong and is displaying the regular E7 instead of the affine E6; the three "branches" should all be symmetrical. — Preceding unsigned comment added by 2605:E000:8517:9700:13F:11FD:2246:9533 (talk) 07:37, 15 November 2015 (UTC)

The affine $G_{2}$ hyperplane arrangemenr looks wrong; the correct picture can be found e.g. at https://www.researchgate.net/publication/339709302_Coxeter_Triangulations_Have_Good_Quality/figures?lo=1 — Preceding unsigned comment added by Math MisterY (talk • contribs) 22:29, 3 November 2023 (UTC)
