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