# --description--
椭圆的定义是给定一个圆心c其中心为M半径为r点G为dGM
椭圆点的构造如下所示。
给定的是M-2000,1500和G8000,1500。给定也是具有中心M和半径15000的圆c。与G和c等距的点的轨迹形成椭圆e。从外部的点P开始绘制两个切线t1和t2到椭圆。让t1和t2接触椭圆的点为R和S.
对于多少格点P角度RPS是否大于45度
# --hints--
`euler246()`应该返回810834388。
```js
assert.strictEqual(euler246(), 810834388);
```
# --seed--
## --seed-contents--
```js
function euler246() {
return true;
}
euler246();
```
# --solutions--
```js
// solution required
```
