摘要:
The sequence of derangements is given by the formula D-0 = 1, D-n = nD(n-1) + (-1)(n) n > 0. It is a classical object appearing in combinatorics and number theory. In this paper we consider such arithmetic properties of the sequence of derangements as: periodicity modulo d, where d is an element of N+, p-adic valuations and prime divisors. Next, we use them to establish arithmetic properties of the sequences of even and odd derangements. (c) 2016 Elsevier Inc. All rights reserved.
