| # --description--
 | ||
| 
 | ||
| Let f(n) represent the number of ways one can fill a 3×3×n tower with blocks of 2×1×1. You're allowed to rotate the blocks in any way you like; however, rotations, reflections etc of the tower itself are counted as distinct.
 | ||
| 
 | ||
| For example (with q = 100000007) :f(2) = 229,f(4) = 117805,f(10) mod q = 96149360,f(103) mod q = 24806056,f(106) mod q = 30808124.
 | ||
| 
 | ||
| Find f(1010000) mod 100000007.
 | ||
| 
 | ||
| # --hints--
 | ||
| 
 | ||
| `euler324()` should return 96972774.
 | ||
| 
 | ||
| ```js
 | ||
| assert.strictEqual(euler324(), 96972774);
 | ||
| ```
 | ||
| 
 | ||
| # --seed--
 | ||
| 
 | ||
| ## --seed-contents--
 | ||
| 
 | ||
| ```js
 | ||
| function euler324() {
 | ||
| 
 | ||
|   return true;
 | ||
| }
 | ||
| 
 | ||
| euler324();
 | ||
| ```
 | ||
| 
 | ||
| # --solutions--

| 
 | ||
| ```js
 | ||
| // solution required
