Supplementary difference sets 2-{½n; k, r; k} are used to construct D-optimal designs for n-= 2 rood 4, where k, r,/t are defined through n. A number of new designs is constructed. The D-optimal design for n = 86 is constructed for the first time. For n~2mod4, n<100 and for the cases n =22, 34, 58

In this paper using circular matrices of order WI with elements circular matrices of order t, we construct block matrices having 2m diagonal blocks of the form (N-3) I,+ 35, and every other element equal to -1, where N = 2mt + 1 and m, t = 1 mod 2. Then by deleting appropriate rows a number of non-
