In other words, a derangement is a permutation that has no fixed points . The number of derangements of a set of size n is known as the subfactorial of n or the n- th derangement number or n- th de Montmort number (after Pierre Remond de Montmort ). Notations for subfactorials in common use include ! n, Dn, dn, or n ยก.
