Consider a distance-regular graph Γ = (X, R) with D ≥ 3 and adjacency matrix A. The subalgebra of M atX(C) generated by A is called the Bose-Mesner algebra M of Γ. Fix a vertex x ∈ X. Let E ∗ 0 , . . . , E∗ D denote the dual primitive idempotents of Γ with respect to x. The subalgebra of M atX(C) ge...
