- Method Detail
  - getBest
```
Permutation getBest()
```
    Get the best permutation found.
    
    Returns:
    
    the permutation that gives the maximal half-matrix string
  - getAutomorphismPartition
```
Partition getAutomorphismPartition()
```
    The automorphism partition is a partition of the elements of the group.
    
    Returns:
    
    a partition of the elements of group
  - getAutomorphismGroup
```
PermutationGroup getAutomorphismGroup()
```
    Get the automorphism group used to prune the search.
    
    Returns:
    
    the automorphism group
  - getFirst
```
Permutation getFirst()
```
    Get the first permutation reached by the search.
    
    Returns:
    
    the first permutation reached
  - firstIsIdentity
```
boolean firstIsIdentity()
```
    Check that the first refined partition is the identity.
    
    Returns:
    
    true if the first is the identity permutation
