Hrayr P. Attarian,Mari Viola-Saltzman2.·7?1 in order 2.·7..We discuss the construction of orthogonal designs using circulant matrices. In particular we construct designs in orders 20 and 28..The weighing matrix conjecture is verified for order 60.

Our main construction method, using unions of cyclotomic classes, gives us upper bounds on m, the number of associate classes of the design, but not exact values for m; we discuss the possible values of m and the circumstances under which m=1, so that the design is in fact balanced.

We establish a recurrence relation to enumerate the sequences with given sum and last term and derive methods for constructing all such sequences with a given sum.
