and/or transitive, where (x;y) 2R if and only if a x 6=y. Not reflexive because it’s not the case 1 6= 1 . Is symmetric because x 6=y and y 6=x. Not antisymmetric because we have x 6=y and y 6=x. Not transitive because we can have 1 6= 2 and 2 6= 1 but not 1 6= 1 . 3

Hadamard Matrices and Designs

x y z w Where x,y,z,w are the numbers of columns of each type. Order of a Hadamard Matrix Theorem V.1.1 - The order of an Hadamard matrix is 1,2 or 4n, n an integer. Proof: (cont) Then since the order is h, ... (1+yx-1) if x≠0. Since y≠0, 1+yx-1 takes on all values except 1, so
