Abstract

Summary: Four Turyn type sequences of lengths 36, 36, 36, 35 are found by a computer search. These sequences give new base sequences of lengths 71, 71, 36, 36 and are used to generate a number of new \(T\)-sequences. The first order of many new Hadamard matrices constructible using these new \(T\)-sequences is 428.
