: perms (v)

Generate all permutations of v with one row per permutation.

The result has size factorial (n) * n, where n is the length of v.

Example

perms ([1, 2, 3])
⇒
  1   2   3
  2   1   3
  1   3   2
  2   3   1
  3   1   2
  3   2   1

Programming Note: The maximum length of v should be less than or equal to 10 to limit memory consumption.
