Let ɼ = (X, R) denote a distance-regular graph with diameter D ≥ 3. Let A0, ..., AD denote the distance matrices of ɼ, and let M denote the subalgebra of Matx (C) generated by A1. Recall that the distance matrices form a basis for M. Fix a vertex x ϵ X. Let T = T (x) denote the subalgebra of Matx (C...
