In order to motivate the Lehmer code, let’s first implement a naive algorithm for computing a permutation of an array. Given the following arrayarr. var arr = [ 'a', 'b', 'c' ]; A simple way of computing a random permutation ofarris: Compute a random numberi, 0 ≤i< 3.arr[i...
which enumerates permutations of ann-element set, it was plausible to expect thatenumerates permutations of [n] according to some natural fourfold classification of indices in [n]. Our first theorem [31, Theorem 2.1] provided two alternative versions of that classification. ...

The StringPerm class has only two data fields, both private: a string array named element to hold the individual atom strings for a particular string permutation element, and an integer field to store the order of the permutation class. I do not implement a default constructor; instead I ...

We introduce and study k-commuting permutations. One of our main results is a characterization of permutations that k-commute with a given permutation. Using this characterization, we obtain formulas for the number of permutations that k-commute with a p

A generalized Young tableau of "shape" , where , is an array of positive integers , for , having monotonically nondecreasing rows and strictly increasing columns. By extending a construction due to Robinson and Schensted, it is possible to obtain a one-to-one correspondence between matrices of ...

A permutation $p$ of size $n$ is an array such that every integer from $1$ to $n$ occurs exactly once in this array. Let's call a permutation an a
