--description--

A 4x4 grid is filled with digits d, 0 ≤ d ≤ 9.

It can be seen that in the grid

6 3 3 0 5 0 4 3 0 7 1 4 1 2 4 5

the sum of each row and each column has the value 12. Moreover the sum of each diagonal is also 12.

In how many ways can you fill a 4x4 grid with the digits d, 0 ≤ d ≤ 9 so that each row, each column, and both diagonals have the same sum?

--hints--

euler166() should return 7130034.

assert.strictEqual(euler166(), 7130034);

function euler166() {

  return true;
}

euler166();
