We have meetings (some may arrive a bit later because of classes) on
Fridays starting at 3:30 PM in Cudahy Hall 301, the HELP DESK partition.

About this class: Levels of participation and registration:
  1. Voluntary class attendance is free and open to ALL MU undergraduates. Putnam Competition registration is encouraged.
  2. Additional registration for MATH 3977 one credit must be completed by the common registration deadline on Tuesday 1 September. Regular class attendance is required.
    In case of registration problems,
  3. Putnam Competition registration is always recommended, but only required for those registered for MATH 3977. For past participants, see all people or some people.

We had an organizational meeting on Friday 4 September at 3:30 PM.
We tried the HELP DESK part of room CU 301, but all chairs had been removed.
So we moved to CU 310, which wasn't in use at that time.

On 20260911 we tried and solved 2020-B2. The following solution is one way to do so. It skips some of our oh-so-valuable partial solutions.
Verbose solution to 2020-ish B2

On 20260918 we tried and solved 2024-A1. The following solution is one way to do so. Recall the importance of partial solutions, like case n = 1.
Verbose solution to 2024 A1

On 20260925 we solved 2021-A1.

On 20260925, we started problem 2022-B1.
