Each matrix is expressed as a human-readable 18 by 18 array of <strong>x</strong>&isin;{0,1,2,3} such that the corresponding elements of each matrix are given by raising the imaginary unit to the power of <strong>x</strong>. Each array is followed by a single row that contains the size of the stabilizer of the matrix.</p>",
