# --description--

|
||
n阶六角形果园是由正六边形中具有边n的点构成的三角形格子。以下是5阶六角形果园的示例：
|
||
|
||
以绿色突出显示的是通过靠近它的点从中心隐藏的点。可以看出，对于5阶六角形果园，中心隐藏了30个点。
|
||
|
||
设H（n）是在n阶六角形果园中从中心隐藏的点数。
|
||
|
||
H（5）= 30.H（10）= 138.H（1 000）= 1177848。
|
||
|
||
找H（100 000 000）。
|

`euler351()`应该返回11762187201804552。
|
||
|
||
```js
|
||
assert.strictEqual(euler351(), 11762187201804552);
|
||
```
