We construct self-orthogonal codes from the row span over F 2 or F 3 of the adjacency matrices of some strongly regular graphs defined by the rank-3 action of the simple unitary group U 4 (3) on the conjugacy classes of some of its maximal subgroups.We establish some properties of these codes and the nature of some classes of codewords.
