A note on products of Relative Difference Sets

  • James A. Davis


Relative Difference Sets with the parameters k = nλ have been constructed many ways (see (Davis, forthcoming; Elliot and Butson 1966; and Jungnickel 1982)). This paper proves a result on building new RDS by taking products of others (much like (Dillon 1985)), and this is applied to several new examples (primarily involving (pi, pj, pi, pi−j)).
