It is possible to find distinguishable permutations using the TI-82 calculator. Place the frequency of each distinguishable item into a list - the following assumes List 1.
(sum L1)! / prod (L1!)
Find the number of distinguishable permutations of the letters in the word "MISSISSIPPI".
| Letter | Frequency |
| M | 1 |
| I | 4 |
| S | 4 |
| P | 2 |
| Total | 11 |
The value, calculated by hand is: 11! / (1! * 4! * 4! * 2!) = 34650
On the calculator, List 1 would be {1,4,4,2}, and then run the above command.
