If I is the 2x2 identity matrix, show that there is an infinite number of matrices X with integer members such that X*X = I.
| m 1+m |
| 1-m -m |
whenever m is an integer, with |m| != 1, satisfies all the conditions of the given problem.
| 1-t 2-t |
| t t-1 |
whenever t is an integer , with t! = 0, 2 also satisfies all conditions of the given problemsatisfy conditions of the problem.
