![Pentagon Equation designed by Zhaoxi (Charles) Xiong and Ryan Thorngren](/sites/default/files/images/tee-shirts-07.jpg "It's based on the pentagon equation. The different fusion diagrams are represented by the branches and the darkened roots, and connected by arrows. The slogan "be consistent" is a reference to the fact that the pentagon equation is one of the consistency equations (for the $F$-symbol) in the description of topological orders in terms of tensor categories. Designed by Zhaoxi (Charles) Xiong and Ryan Thorngren")
