$12n$ musicians participate at a music festival. On the first day, they form $3n$ quartets and practice all day.

It is a disaster. At the end of the day, all musicians decide they will never again agree to play with any member of their quartet.

On the second day, they form $4n$ trios, with every musician avoiding any previous quartet partners.

Let $f(12n)$ be the number of ways to organize the trios amongst the $12n$ musicians.

You are given $f(12)=576$ and $f(24)mod1000000007=509089824$.

Find $f(600)mod1000000007$.
