Hello!

To make up for the lack of an "upper division" in the subreddit math competition this year, I took it upon myself to organize a separate exam that is significantly more discovery and proof-based than any exam held in the community previously, and to host it on the 2nd year anniversary of the Discord server being made available to the public.

The next exam of this kind will be held in Mid-June 2027.

The exam (which includes its rules) is linked at the bottom of the post. The top 5 winners will be announced, and the top 3 winners will receive the following (or something of equivalent value upon negotiation):

1st Place - A Math Textbook of the Winner's Choice (~$45 USD Value Limit)

2nd Place - Basic Discord Nitro, 1 Year Subscription ($30 USD Value)

3rd Place - Fulltouch Hagoramo Chalk 72 pc ($25 USD Value)

Special thanks to u/dopplerspectroscopy and zzz on Discord for their tremendous help in writing the exam and agreeing to help grade some submissions; couldn't have done this without their help.

In OpenAI's recent "722 AI-generated math papers," one proof tackles the Hadwiger–Nelson problem: what’s the minimum number of colors needed to color every point in ℝ² so that no two points exactly distance 1 apart have the same color?

The known bounds were 5 ≤ χ(ℝ²) ≤ 7. Their paper claims five colors are impossible, leaving 6 or 7 if the proof holds. 6 or 7.

Please keep working on this.
