SG::RRep2Perm -- calculates a permutation from its matrix in the regular representation

Call(s)


SG::RRep2Perm(m)

Parameters

m- a square matrix

Introduction

The SG::RRep2Perm function calculates a permutation from its matrix in the regular representation, that is to say the matrix of the linear operator "left multiplication by perm".

Example 1

>> muEC::SG::Perm2RRep( [3,1,2] );
                          +-                  -+
                          |  0, 0, 0, 1, 0, 0  |
                          |                    |
                          |  0, 0, 1, 0, 0, 0  |
                          |                    |
                          |  0, 0, 0, 0, 0, 1  |
                          |                    |
                          |  0, 0, 0, 0, 1, 0  |
                          |                    |
                          |  1, 0, 0, 0, 0, 0  |
                          |                    |
                          |  0, 1, 0, 0, 0, 0  |
                          +-                  -+
>> muEC::SG::RRep2Perm( % );
                                 [3, 1, 2]
