On \((p^ a,p^ b,p^ a,p^{a-b})\)-relative difference sets
New bounds on the exponent and rank of abelian relative difference sets in \(p\)-groups are proved. These bounds are used to prove the non-existence of certain splitting difference sets in 2-groups. The parameters (16, 4, 16, 4) are studied in detail.
