## Description
|
||
<section id='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 ?
