--description--

Having three black objects B and one white object W they can be grouped in 7 ways like this:

(BBBW)(B,BBW)(B,B,BW)(B,B,B,W)

(B,BB,W)(BBB,W)(BB,BW)

In how many ways can sixty black objects B and forty white objects W be thus grouped?

--hints--

euler181() should return 83735848679360670.

assert.strictEqual(euler181(), 83735848679360670);

function euler181() {

  return true;
}

euler181();
