# --description--
|
||
|
||
For a positive integer n, let σ2(n) be the sum of the squares of its divisors. For example,
|
||
|
||
σ2(10) = 1 + 4 + 25 + 100 = 130.
|
||
|
||
Find the sum of all n, 0 < n < 64,000,000 such that σ2(n) is a perfect square.

`euler211()` should return 1922364685.
|
||
|
||
```js
|
||
assert.strictEqual(euler211(), 1922364685);
|
||
```
