google "counting anagrams"
hmmm...most of the links from google are about programing anagram solvers, etc. Not really about the counting problem here.
The very first result from google is this
It gives the equation where is the length of the word, is the number of times the first letter is in the word, and so on...
So for PARRAMATTA its
Hey sorry, I understand how to do it for ten letter words. That is, the number of annograms for the word. However I dont understand how to the rest of the quetion. 9 letter words and then 8 letter words from the original 10 letter word PARRAMATTA.
There are 5 different letters in the word. Dump one of one type and repeat the above process for 9 letters. Then dump one of a different type...
For 8 letters, think of what you would be left with if you got rid of PA, then PR, then PM...
