If n > 1 is an integer, a permutation  the group of permutations of the set of integers from 1 to n  is called a derangement if it has no fixed points; that is, for k = 1 to n.
The number of derangements in S_{n} may be determined by "inclusionexclusion." The proportion of elements in S_{n} which are derangements is which is a partial sum of the Taylor series for 1/e. Last fiddled with by Dr Sardonicus on 20211030 at 15:33 Reason: xignif topsy
