Permutation (nPr) and Combination (nCr)

These functions make it possible to perform permutation and combination calculations.

n and r must be integers in the range of 0 ≦ rn < 1 × 1010.

Numbers cannot be duplicated within the same 4-digit value (1234 is allowed, but 1123 is not).

  • 7(nPr) 4
  • 840.
