Consider the python code below: Numbers = [1, 2, 3, 4, 5, 6] Counter = 0 for i in Numbers: for j in Numbers: if j != i: for k in Numbers: if k != i and k != j: print(i, j, k) Counter = Counter +1 print(Counter) (a) What is the above code counting? (Permutations/combinations with/without repetition) (b) If Numbers has nentries, give a closed formula for the number of objects being counted.
