Some properties of the twisted Grassmann graphs
This note investigates some properties of the twisted Grassmann graphs. These graphs have the same parameters as the Grassmann graphs \(J_q(2e+ 1,e)\), but are not vertex-transitive. Full automorphism groups of these graphs have been determined. It is also shown that these automorphism groups do not have distance-regular antipodal covers. It is further shown that they are not the halved graphs of bipartite distance-regular graphs.
