Description: Abstract: "We give two constructions for semi-regular relative difference sets (RDSs) in groups whose order is not a prime power, where the order u of the forbidden subgroup is greater than 2.  No such RDSs were previously known.  We use examples from the first construction to produce semi-regular RDSs in groups whose order can contain more than two distinct prime factors.  For u greater than or similar to 2 these are the first such RDSs, and for u=2 we obtain new examples."
