Is H closed under addition? If it is, enter CLOSED. If it is not, enter two matrices in H whose sum is not in H, using a comma separated list and [1 2] [5 6] 3 syntax such as [[1,2], [3,4]], [[5,6],[7,8]] for the answer (Hint: to show that H is not closed under addition, it is 8 sufficient to find two nilpotent matrices A and B such that (A + B)" # 0 for all positive integers n.)
