The purpose of the Math Department Colloquium Series is to bring our entire department together as a community to enjoy a lecture on mathematics. Everyone interested in mathematics is welcome to attend.

The organizers for the 2024/2025 academic year are Dr. Katrina Honigs, Dr. Jessica Stockdale, and Dr. Paul Tupper.

## Upcoming Colloquium Talks

### Dr. Jim Davis (University of Richmond)

*The search for difference sets in groups of order 256*

September 24, 2024

12:30pm - 1:30pm

Big Data Hub – Presentation Studio (ASB 10900)

Difference sets have played an important role in theoretical and practical problems for almost a century. I will give a gentle introduction to difference sets, and I will give several examples why you ought to care about them. I will then describe a decades long search for difference sets in the 56,092 nonisomorphic groups of order 256. I will also describe the next size up, groups of order 1024, which will require us to search 49,487,367,289 nonisomoprhic groups. I will provide a possible road map for working on this case.
