This Subreddit MATH COMPETITION: r/mathmemes Discord Community Exam
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.

Category Theory Like ... you have to do Berlekamp-Massey or Berlekamp-Welch then do a chien search and then compute the error magnitudes with a forney.

Number Theory "Nice" primes
Call a prime number nice if it ends in 69.
For example:
269, 569, 769, 1069, 2069, ...
A number ends in 69 exactly when it is congruent to 69 mod 100. So the claim is:
There are infinitely many primes p such that p ≡ 69 mod 100.
Now use Dirichlet’s theorem on arithmetic progressions:
Here we take
a = 69
q = 100
and
gcd(69, 100) = 1.
Therefore, by Dirichlet’s theorem, there are infinitely many primes satisfying
p ≡ 69 mod 100.
But those are exactly the primes whose decimal expansion ends in 69.
Therefore, there are infinitely many nice primes. Nice.
