## Abstract A method is described of constructing a class of self‐complementary graphs, that includes a self‐complementary graph, containing no __K__~5~, with 41 vertices and a self‐complementary graph, containing no __K__~7~, with 113 vertices. The latter construction gives the improved Ramsey num
