# Combinatorics monster???

**Discrete Mathematics**Level 5

How many words can be made with the letters of the word **MATHEMATICS** so that the M's and T's come alternatively and the letters appear exactly **2015** number of times as they appear in the word MATHEMATICS?

Akul, not so good in mathematics, decides to take help of his brilliant friends. Help him please...

The answer is in the form \( d\times(\frac{a!}{b!\times c!\times e!^{5}})\)

where a, b, c, d and e are integers and d is the minimum integer possible. Give your answer as a+b+c+d+e.

**Details and Assumptions**

- By alternatively I mean that there is only one T between two cosecutive M's and vice versa.
- Letters appear 2015 times means that if a particular letter appears n times in word MATHEMATICS, it will appear
**2015n**times in the word formed.
