Re: permutation

Hi mukesh;

The vowels are considered to be all alike. There are also 2 T's .Now it is a standard "MISSISSIPPI" problem.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Re: permutation
