template<typename Perm> class permutation_traits¶

using value_type = typename Perm::value_type¶: The whole specialization of this traits class only exists if this type exists.

static value_type get(const Perm &p, value_type i)¶

Returns: the image of i under p using p.get_(i).

static Perm make(std::size_t n)¶

Returns: a new permutation of size n using Perm(n).

static Perm make_identity(std::size_t n)¶

Returns: a permutation created with make and initialized as the identity.

static void put(Perm &p, value_type i, value_type image)¶: Sets the image of i to image using p.put_(i, image).

static std::size_t degree(const Perm &p)¶

Returns: p.degree_()

static Perm make_inverse(const Perm &p, std::size_t n)¶

Returns: a permutation created with make where the inverse of p has been copied into.
