Problem Statement

For every nn in the set N={1,2,}\mathrm{N} = \{1,2,\dots \} of positive integers, let rnr_n be the minimum value of cd3|c-d\sqrt{3}| for all nonnegative integers cc and dd with c+d=nc+d=n. Find, with proof, the smallest positive real number gg with rngr_n \leq g for all nNn \in \mathbb{N}.
