where 
stands for the elementary transposition 
computed by muEC::SG::SgTranspo(i,n). muEC::SG::Rd2Perm – permutation from a decomposition
computes a permutation from its decomposition

muEC::SG::Rd2Perm(rd, <n>)
Parameters:
|
rd: |
any list denoting a decomposition |
|
n: |
degree of a symmetric group (positive integer) |

Details:
The muEC::SG::Rd2Perm function calculates the permutation corresponding to the list rd, the entries of rd being interpreted as simple transpositions. Let , then muEC::SG::Rd2Perm(rd)= where stands for the elementary transposition computed by muEC::SG::SgTranspo(i,n).
When the second argument is not present, n is the smallest possible degree.
The decomposition needs not to be reduced.
muEC::SG::Rd2Perm( [1,2,1], 5 );
muEC::SG::Rd2Perm( [1,2,1] );
