ABSTRACT
Chapter 5, the enumeration of the permutations of n with a given number
of xed points and the permutations of n of a given rank was carried out.
Also, the (linear) permutations of n and the circular permutations of n
with a given number of successions of points were enumerated. Further, the
permutations of a nite set of n elements may be distinguished according to
their decomposition into disjoint cycles. A host of interesting enumeration
problems emerges from this consideration.
