Hello everyone!

We are back with another live Math Contest on Repovive!

This time, we're expanding our problem set even further. Repovive Math Contest Round 3 will feature problems from Combinatorics, Algebra, and Number Theory!

Our goal is to bring the excitement of competitive programming to proof-based mathematics. You solve mathematical problems, write your proofs, submit them for live judging, and compete on a live leaderboard.

Whether you enjoy combinatorial arguments, clever algebraic ideas, or beautiful number-theoretic observations, we hope you'll find something interesting!

• Start Time: Sunday, 25 October 2026, 15:05 (UTC)
• Duration: $$$2$$$ hours, $$$30$$$ minutes
• Problems: $$$5$$$
• Points: $$$500,\ 1000,\ 1500,\ 2000,\ 2500$$$
• Registration: https://repovive.com/contests/m3

The contest is rated for everyone.

Rules and judging

The format remains the same as in our previous Math Contests.

Participants submit written mathematical solutions, which are evaluated by 5 GPT-6 judge agents. Judging is currently binary, meaning each submission receives either Accepted or Rejected.

Rejected submissions do not add any extra penalty, and you may make at most 15 submissions per problem.

Any use of AI during the contest is prohibited, including for translation. The platform can translate problem statements, and solutions may be written in any language.

We are continuing to improve the judging system based on feedback from previous rounds.

We're excited to bring Number Theory into the series alongside Combinatorics and Algebra!

We hope you enjoy the contest.

See you on the leaderboard!
