[math-fun] Re: covering all N with squares (2nd degree polynomialswith integer coeffs.).

No, rule 1, only polynomials with integer coeffs. rule 2, there can be some overlap. rule 3, avoid the first trivial column. rule 4, only N, not Z. I wanted to explicitely write down a set of polynomials with the desired results, as we know pol. of degree 2 are sparse compared to all integers, I was wondering if it was plain impossible or trivially possible.
