  <dc:description>The files contain the quaternary complex Hadamard matrices of order 18 classified in the work "Patric R. J. Östergård and William T. Paavola, Quaternary Complex Hadamard Matrices of Order 18".

Each file bh18-tn.txt contains the matrices of type n up to Hadamard equivalence. Each matrix is expressed as a human-readable 18 by 18 array of x∈{0,1,2,3} such that the corresponding elements of each matrix are given by raising the imaginary unit to the power of x. Each array is followed by a single row that contains the size of the stabilizer of the matrix.</dc:description>
