Consider the number 50.

502 = 2500 = 22 × 54, so φ(2500) = 2 × 4 × 53 = 8 × 53 = 23 × 53. 1

So 2500 is a square and φ(2500) is a cube.

Find the sum of all numbers n, 1 < n < 1010 such that φ(n2) is a cube.

1 φ denotes Euler's totient function.

--hints--

euler342() should return 5943040885644.

assert.strictEqual(euler342(), 5943040885644);

function euler342() {

  return true;
}

euler342();
