Enumerations | |
| enum | regina::PermCodeType { regina::PERM_CODE_IMAGES = 1 , regina::PERM_CODE_INDEX = 2 } |
| Represents the different kinds of internal permutation codes that are used in Regina's various Perm<n> template classes. More... | |
Functions | |
| constexpr char | regina::digit (int i) |
| Returns the character used to express the integer i in a permutation. More... | |
| constexpr int64_t | regina::factorial (int n) |

Variables | |
| constexpr int | regina::detail::countPermClasses [17] |

Deals with permutations of {0,1,...,n-1}.
This is the only header that you need to include for Regina's permutation classes. It will automatically bring in all implementation details and specialisations.
