In a hypothetical wireless system, five adjacent frequency bands ( 1 f , 2 f , 3 f , 4 f , 5 f ) are allowed for frequency hopping sequences. Enumerate how many different hopping sequences are possible and prove their correctness.

What will be an ideal response?


If we have 5 bands we can have 5! = 120 hopping sequences.
