$\displaystyle A^n = \left ( \begin{matrix} \Lambda ^n & n \Lambda ^{n  1} & 1 + 2 \Lambda + \dots + (n  1) \Lambda ^{n  2} \\ 0 & \Lambda ^n & 1 + \Lambda + \Lambda ^2 + \dots + \Lambda ^{n  1} \\ 0 & 0 & 1 \end{matrix} \right )$ You can use induction to prove this formula. Did that answer your question? Dan
