Q: Decide whether it is true that if n is a positive integer and d is a divisor of φ(n), then there is an integer a with ordna=d. Give reasons for your answer.
Don't know how to do this, please any one help?? Thanks very much.

Of course.
The order of any integer relatively prime to must be a divisor of . As you have seen not all integers are primitive roots so there are some that satisfy what you said.
