Form a 5 x 5 matrix by writing the integers 1, 2, 3,4, 5 into each column in any order

Chapter 7, Problem 31

(choose chapter or problem)

Form a 5 x 5 matrix by writing the integers 1, 2, 3,4, 5 into each column in any order you like. An example is A =5 1 2 2 1 1 4 3 3 2 3 3 5 4 3 2 5 4 1 4 4 2 1 5 5(Optional question for combinatorics aficionados: How many such matrices are there?) Take higher and higher powers of the matrix you have chosen (using technology), and compare the columns of the matrices you get. What do you observe? Explain the result. (Hint: Exercise 30 is helpful.)
