Can I clarify?

56 letters including 10 spaces and a question mark.

allowing for duplicates (i.e. 3 h's, 6 n's)
and the fact that I can't tell the difference between nnnnnn and nnnnnn
then you have

        = 56! / (10! * 3! * 5! * 6! * 6! * 3! * 2! * 4! * 2! * 2! * 2! * 2!
* 3!)

        = 1.898648171e+55 different ways?
