| Abstract: | Identical elements are divided into r disordered groups(in each of which there is at least one element), Sum of all different grouping schemes is called identical elements grouping number,Signed asM.According fo the characteristics and the recurrence relations of the grouping numbers ,a grouping function can be defined and then a simple calculation method for identical element grouping number will be acquired. |
| Keywords: | ball-box model identical element grouping number M (n r) grouping function d (n ) |
