Documentation

Permutation class. Mathematical interface to a permutation providing the standard operation and some extra stuff.

Perm(size_t ssize, perm_t* mmap)

Constructor. Create permutation in S_ssize with mappings mmap.

Perm(size_t size)

Constructor. Create identity permutation in S_ssize.

Perm()

Constructor. Create identity in S_5.

perm_t map(perm_t el) const

Operation. Get result of the operation on el.

size_t get_size() const

Size. Get the n in S_n.

bool operator==(const Perm &p) const

Equal. this == p ?

bool operator!=(const Perm &p) const

Unequal. this != p ?

Perm& operator*(const Perm &p) const

Multiplication. this * p

void print() const

Print. Nice output of this.

int sign() const

Sign. Return sign of this.

int ord() const

Order. Return order of this in S_n.

Perm& inv() const

Inversion. Return this^(-1).
