摘要
We construct distance-regular graphs with the same - classical - parameters as the Grassmann graphs on the e-dimensional subspaces of a (2e + 1)-dimensional space over an arbitrary finite field. This provides the first known family of non-vertex-transitive distance-regular graphs with unbounded diameter.
