Abstract: We study the existence of nontrivial (2 m, k, λ)-difference sets in dihedral groups. Some nonexistence results are proved. In particular, we show that n = k - λ is odd and φ{symbol}(n)/n < 1/2. Finally, a computer search shows that, except 5 undecided cases, no nontrivial difference set exists in dihedral groups for n ≤ 106. © 1992 Kluwer Academic Publishers.
