The major challenge when working with permutations is that the factorial function gets very, very large very, very quickly. The BigInteger data type was introduced in the .NET Framework 4.0; it ...

Abstract: A new decoding method is presented for permutation codes obtained from distance-preserving mapping algorithms, used in conjunction with M-ary FSK for use on power- line channels. The new ...

Abstract: We address an important issue in the design of concentric permutation code based vector quantizers to select the optimal integer partitions. We establish that, for concentric permutation ...

Code to generate all permutation-matrix solutions to the Yang-Baxter up to dimension 25 by pruned depth-first-search. Also, the solutions. The text files contain all the permutations satisfying the ...
