Crate permutations

Permutations.

Constructs single permutations and provides operations such as composition, inverse and exponentiation. Allows iterate over permutations in lexicographic order and alos to access them by index.

Crate Status

Experimental

Limitations

• Depending on the number of bits in usize you can iterate over permutations of at most 20 elements for 64 bits, 12 elements for 32 bits, or 8 elements for 16 bits. The same applies to indexed access.

Crate Feature Flags

• random
  • Off by default.
  • Adds a dependency to the rand crate.
  • Adds the method random to generate a random permutation of n elements.
