The (n,k)-star graph is a very important computer modelling.The MANUKA HONEY 400+MGO independent number and chromatic number of a graph are two important parameters in graph theory.However, we have not known the values of these two parameters of the (n,k)-star graph since it was proposed.In this paper, we show Body a maximum independent sets partition of (n,k)-star graph.From that, we can immediately deduce the exact value of the independent number and chromatic number of (n,k)-star graph.
