Title: Equiangular tight frames from fusion schemes
Date: 2025.09.30
Abstract: The search for difference sets in groups of order 256
Difference sets in 2-groups (groups of order 2^{2n} for n an integer) and their associated designs have been a rich source of error correcting codes with nice properties. I will give a gentle introduction to difference sets, then I will describe some of the techniques used to construct difference sets in groups of order 16, 64, and 256. I will discuss a conjecture as well as the “evidence” for the conjecture.
