These are partitions of [ l ] Ο Ν 1 , 2 , . . . , l Ν into n blocks such that no four-term subsequence of [ l ] induces the mentioned pattern and each k consecutive numbers of [ l ] fall into dif ferent blocks . These structures are motivated by Davenport -Schinzel sequences . We summarize and exten
It is shown in this note that it can be recognized in polynomial time whether the vertex set of a finite undirected graph can be partitioned into one or two independent sets and one or two cliques. Such graphs generalize bipartite and split graphs and the result also shows that it can be recognized
