I think n = 5, 5! = 120. But "_B_I" is the same as "_I_B" and should be removed from count.
Hello.
I'm trying to find a formula to find the number of possible results.
Items:
- BLANK
- _B
- _I
- _U
- _Brd
Order matters and no reputation. Looking for all unique possibilities.
NAME (THIS NEVER CHANGES AND CAN BE IGNORED)
1.58mm(1/16)_Op
Example output:
1.58mm(1/16)_Op
1.58mm(1/16)_Op_B
1.58mm(1/16)_Op_B_I
I tried to write them all out and i think there is 14?
Any
help would be great.
Thanks
