PermutationGroup

public PermutationGroup()

Method Details

addPermutation

public void addPermutation(List<Integer> permutation)

getPermutation

public List<Integer> getPermutation(int index)

getOrder

public int getOrder()

completeGroup

public void completeGroup()

Specified by:

iterator in interface Iterable<List<Integer>>

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
