Abstract:Stirlingnumber of the first kind nn-i can be expressed by combination number. In this paper,we obtained recurrence relation of Stirling number of the first kind in terms of combination number representation.Thus,we gave the explicit formula of nn-ifor all i∈N
Key words: Stirling number of the first kind; combination number; like-pascal triangle
