## Indecomposable Soergel bimodules for Universal Coxeter groups

joint with Ben Elias ; with an appendix by Ben Webster, **Trans. Amer. Math. Soc**.** **369 (2017), 3883-3910.
We introduce the **multicolored Temperley-Lieb 2-category**. Using it, we find the explicit numbers for which "Soergel's conjecture in positive characteristic for Universal Coxeter systems" fail.
