Let n and D be positive integers with n 3, and let H(D n) denote the Hamming graph. Recall the graph H(D n) is distance-regular of diameter D. Let X denote the vertex set of H(D n), and let MatX(C) denote the C-algebra of matrices with rows and columns indexed by X. Let A 2 MatX(C) denote the adjace...
