... original formula for q. Recall that our proof of the formula we had inExercise 1.4-5 did not explain why the product of three factorials appeared in the denominator,it simply proved the formula ... distinct elements. There are n choices for the first number in the list. For each way of choosing the first element, there are n −1choices for the second. For each choiceof the first two elements, ... theproduct in the denominator of the formula in Exercise 1.4-5 for the number of labellings withthree labels is what it is, and could generalize this formula to four or more labels.Equivalence...
