Let denote a distance-regular graph with diameter D 3. Assume has classical parameters (D, b, α, β) with b < -1. Let X denote the vertex set of and let A ∈ Mat X (C) denote the adjacency matrix of . Fix x ∈ X and let A \* ∈ Mat X (C) denote the corresponding dual adjacency matrix. Let T denote the s
