Relative difference sets with \(n=2\)
The authors investigate whether \((m, k, 2\lambda)\) difference sets can be extended to \((m, 2, k, \lambda)\) relative difference sets. They prove that the extension is impossible for many well-known difference sets, and conjecture that the extension is impossible unless the difference set is trivial or has the parameters of the complement of a Singer difference set with even dimension.
