## Team Brain Potion

In addition to the individual competition, students in groups of up to 5 students were able to compete in a written team competition before the start of the convention. More information about the Team Brain Potion Contest, including an introduction to the topics, is available here. There were two levels for the Team Brain Potion Contest.

### Division M

The Division M Team Brain Potion Contest covered Taxicab Geometry and an introduction to metrics. Students were challenged to explore a different way to measure the distance between two points and how this affects some standard geometric concepts. They were then introduced to the idea of “distance” between arbitrary objects, in this case binary bytes. The full Division M task is available by clicking here.

The standout submission came from an individual, Sophia Zhang, congrats! Sophia’s submission will be available online soon!

### Division H

The Division H Team Brain Potion Contest covered symmetry and an introduction to groups. Students were challenged explore symmetries of regular polygons and explain how composing these symmetries works. They were then introduced to the more general idea of a permutation group and explored how to compose different permutations. The full Division H task is available by clicking here.

The standout submission came from the team consisting of Andrew Pu, Benjamin Yi, Daniel Xu, Jiasheng Zhou, and Konnie Duan, congrats! The teams submission will be available online soon!
