P(n,s) denotes the number of permutations of 1,2,...n that have exactly s sequences. Canfield and Wilf [ math.CO/0609704 ] recently showed that P(n,s) can be written as a sum of s polynomials in n. We determine these polynomials explicitly and also obtain explicit expressions for ...

A General Note: Formula for Finding the Number of Permutations of n Non-Distinct Objects If there are nn elements in a set and r1r1 are alike, r2r2 are alike, r3r3 are alike, and so on through rkrk, the number of permutations can be found by n!...
We are given a sequence : [1,2,...N]. Lets consider all the permutations of the above sequence. Now, a good permutation is defined as the one in which there is atleast one pair of numbers such that a[i]+1=a[i+1]. How to count the number of good permutations ? This problem ...
