SG::MultPerm -- multiply permutations

Call(s)


SG::MultPerm(perm1,perm2)

Parameters

perm1, perm2- any lists denoting permutations

Introduction

The SG::MultPerm function calculates the product of a sequence (of arbitrary length) of permutations.

SG::MultPerm(perm1, perm2) computes perm1(perm2).

Permutations need not to belong to the same symmetric group: Sn is embedded into Sn+1 by adding the fixed point n+1.

Example 1

>> muEC::SG::MultPerm( [1,3,2], [2,3,1] );
                                 [3, 2, 1]
>> muEC::SG::MultPerm( [1,3,2], [2,3,1], [1,3,2,4] );
                               [3, 1, 2, 4]
