Hello everyone!

We are back with another live Math Contest on Repovive!

After two rounds focused on combinatorics, we are expanding the problem set. This time, the contest will feature problems from both Combinatorics and Algebra!

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

Whether you enjoy clever algebraic ideas or beautiful combinatorial arguments, we hope you will find something interesting in this round!

• Start Time: Sunday, 18 October 2026, 13:35 (UTC)
• Duration: $$$2$$$ hours, $$$30$$$ minutes
• Problems: $$$5$$$
• Points: $$$500,\ 1000,\ 1500,\ 2000,\ 2500$$$
• Registration: https://repovive.com/contests/m2

The contest is rated for everyone.

Rules and judging

The rules are currently the same as in the previous Math Contest. You can read them here:

https://repovive.com/contests/m2/rules

Participants submit written mathematical solutions, which are evaluated by 5 GPT-6 judge agents. Judging remains 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. If any rules change before the contest, we will announce the changes on the rules page.

We are excited to introduce Algebra into the series alongside Combinatorics, and we hope you enjoy the new mix of problems!

See you on the leaderboard!

UPD1: The contest has been moved one hour earlier. The new start time is Sunday, 18 October 2026, 13:35 UTC. All other details remain unchanged.
