Transitive distance-regular graphs from the unitary groups U(3, 4), U(4, 3) and U(5, 2)

In this paper we classify distance-regular graphs, including strongly regular graphs, admitting a transitive action of the unitary groups U(3, 4), U(4, 3) and U(5, 2) for which the rank of the permutation representation is at most 15. We give details about the constructed graphs. The graphs constructed in the paper were known before, but have been obtained in a different way.
