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

1. Are there any restrictions on the cocefficients, or can they be arbitrary complex numbers? 2. As long as each natural number occurs somewhere in the array, does it matter what else is in the array? --Dan ------------------------------------------------------ Simon says: << ... let my try to restate the problem let's make a square array of numbers from wich each row is a 2nd degree pol. : apart from the first column, does the array covers ALL natural numbers with possibly some overlap?
