# --description--

How many triangles are there with integral sides, at least one integral angle (measured in degrees), and a perimeter that does not exceed 108?

# --hints--

`euler279()` should return 416577688.

```js
assert.strictEqual(euler279(), 416577688);
```

# --seed--

## --seed-contents--

```js
function euler279() {

  return true;
}

euler279();
```

# --solutions--

```js
// solution required
