The incidence matrices corresponding to a nil-algebra of finite index n can be used to determine the nilpotency. We find the smallest positive integer m such that the sum of the incidence matrices P P hn; mi P is invertible. In this paper, we give a dierent proof of the case that the nil-algebra of index 2 has nilpotency less than or equal to 4.
