Relative difference sets (RDS) describe finite geometries with large automorphism groups. Difference sets are well studied and there are computational methods for constructing and (sometimes) classifying them. We will present a difference set construction corresponding to almost perfect non-linear (APN) functions and discuss the possibilities of gaining knowledge by translating problems from APN to RDS and back again.
