Practical application of the drawer principle & free difference set

  • Both the general form of the drawer principle and the free difference set of integral sets can be applied to solve some practical problems concerning combinatorial theory.In this paper,the writer would like to illustrate the relationship between the drawer principle and the free difference sets by demonstrating some typical examples so as to make it more or less significant to the combinatorial theory.
