# --description--
|
||||
|
||||
An $n × n$ grid of squares contains $n^2$ ants, one ant per square.
|
||||
|
||||
All ants decide to move simultaneously to an adjacent square (usually 4 possibilities, except for ants on the edge of the grid or at the corners).
|
||||
|
||||
We define $f(n)$ to be the number of ways this can happen without any ants ending on the same square and without any two ants crossing the same edge between two squares.
|
||||
|
||||
You are given that $f(4) = 88$.
|
||||
|
||||
Find $f(10)$.
|
||||
|
||||
# --hints--
|
||||
|
||||
`migratingAnts()` should return `112398351350823100`.
|
||||
|
||||
```js
|
||||
assert.strictEqual(migratingAnts(), 112398351350823100);
|
||||
```
