We give new sets of sequences with entries from {0; ยฑa; ยฑb; ยฑc; ยฑd} on the commuting variables a; b; c; d and zero autocorrelation function. Then we use these sequences to construct some new orthogonal designs. Among the others, the following new four variable orthogonal designs in order 36 are cons

โฆ Synopsis
A result of Robinson states that no OD(n; 1; 1; 1; 1; 1; n-5) exists for n ยฟ 40. We complement this result by showing the existence of OD(n; 1; 1; 1; 1; 1; n -5) for n = 32; 40. This includes a resolution to an old open problem regarding orthogonal designs of order 32 as well. We also obtain a number of new orthogonal designs of order 32.
