A permutation of n ordered objects in which no object is in its natural place is
called a derangement (or sometimes, a complete permutation) and the number of
such permutations is given by the subfactorial in. Using the binomial expression,

A subfactorial is formed in two steps from the previous subf actor ial. Using !N for
subfactorial N, we have as a recursion formula !N= N • !(N - 1) + (-1)N with
subfactorial zero defined as unity. We would express the rule in words by saying
that in ...
