We study an analogue of a classical arithmetic problem over the ring of polynomials. We prove that \ (m = 5\) is the minimal number such that the sums of any two distinct polynomials in a set of \ (m\) polynomials over \ (F₂x\) cannot all be of the form \ (xᵏ (x+1) ^\).
Luis Angel Cruz Gallardo (Thu,) studied this question.
