5900f4551000cf542c50ff68 Problem 233: Lattice points on a circle 5 301877 problem-233-lattice-points-on-a-circle

--description--

Let f(N) be the number of points with integer coordinates that are on a circle passing through (0,0), (N,0),(0,N), and (N,N).

It can be shown that f(10000) = 36.

What is the sum of all positive integers N ≤ 1011 such that f(N) = 420 ?

--hints--

euler233() should return 271204031455541300.

assert.strictEqual(euler233(), 271204031455541300);
