Schade, Tilla The linear 3-cover of the Hermitean forms graph on 81 vertices. (English) Zbl 0993.05146 Ars Comb. 54, 187-222 (2000). Linear graphs, a special case of Cayley graphs, can be represented with help of affine and projective geometries. The Hermitean forms graphs are series of linear distance-regular graphs. A new construction, based on the geometric representation, for the linear 3-cover of special Hermitean forms graphs (strongly regular graphs) is given.
