Please help. Found 2 solutions by Boreal, ikleyn:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! start with 11 letters that are unique, and that would be 11!
but M is alone and there are 4 I, 4 S, and 2 P (and 1 M)
These lower the count since they are not unique
11!/4!2!4!!!
or 11!/1152=34650 ways
