# --description--
考虑数字50. 502 = 2500 = 22×54因此φ2500= 2×4×53 = 8×53 = 23×53.1因此2500是正方形而φ2500是立方体。
找到所有数字的总和n1 <n <1010使得φn2是立方体。
1φ表示欧拉的函数。
# --hints--
`euler342()`应该返回5943040885644。
```js
assert.strictEqual(euler342(), 5943040885644);
```
# --seed--
## --seed-contents--
```js
function euler342() {
return true;
}
euler342();
```
# --solutions--
```js
// solution required
