SG::FactorPerm --
tests whether a permutation factorizes into a direct product
Call(s)
SG::FactorPerm(perm)
Parametersperm | - | any list denoting a permutation |
Introduction
Given a permutation perm in Sn, the SG::FactorPerm function
tests whether perm belongs to a Young sub-group
Si x Sj
The result is a couple Test,l where Test is a boolean and l
the minimal length of a left block.
Example 1>> muEC::SG::FactorPerm( [3,1,2,5,4,7,6] );
TRUE, 3
