... We may take S = {1, 2, . . . , 1000} (because 1000 is not squarefree so does not contribute to the count) in order to use some of calculations in (a). As in (a), let Ad denote the set of numbers in S that are divisible by d. For relatively prime c, d we have Ac ∩ Ad = Acd . For d > 1000 we have Ad = ...

Random permutation statistics

The statistics of random permutations, such as the cycle structure of a random permutation are of fundamental importance in the analysis of algorithms, especially of sorting algorithms, which operate on random permutations. Suppose, for example, that we are using quickselect (a cousin of quicksort) to select a random element of a random permutation. Quickselect will perform a partial sort on the array, as it partitions the array according to the pivot. Hence a permutation will be less disordered after quickselect has been performed. The amount of disorder that remains may be analysed with generating functions. These generating functions depend in a fundamental way on the generating functions of random permutation statistics. Hence it is of vital importance to compute these generating functions.The article on random permutations contains an introduction to random permutations.
