Let {u100000}(X R) denote a distance-regular graph and let A 2 MatX(R) denote the adjacency matrix of {u100000}. We define a matrix B 2 MatX(R) to be A-like whenever both (i) BA = AB and (ii) for all x y 2 X that are not equal or adjacent, the (x y)-entry of B is zero. Let L denote the subspace of...
