4. Let A [2] [2] where all entries are in the finite field Z3. There are [1] [0] only 34 different 2 2 matrices with entries, so when you compute powers of A, some power must eventually repeat. If Am = An and A is invertible,, then An-m I. By matrix multiplication, find the smallest positive integer p for which A I. Then invent an invertible matrix B for which has a different value, like 2 or 6. = "
