Abstract
In this paper we modify a fundamental block construction of Kharaghani and Seberry and show how to use certain circulant -matrices of odd order to construct a complex Hadamard matrix of order . In particular, for we use computer-aided methods to discover the necessary circulant matrices, and consequently give a construction of a complex Hadamard matrix of order for the first time.
