Abstract
Let Y=(X, {Ri}0≦i≦d) be an association scheme whose parameters coincide with those of the association scheme Her (d, q) of Hermitian forms in d-dimen-sional space over the field GF(q2). Suppose that every edge of the distance- regular graph Γ=(X, R1) is contained in a clique of size q. It is shown that if d≧3 then Y is isomorphic to Her (d, q). In the case d=2 a generalized quadrangle with the parameters (q, q2) is reconstructed from Y.
