Rational Solutions of the Sasano System of Type $A_5^{(2)}$
  In this paper, we completely classify the rational solutions of the Sasano system of type $A_5^{(2)}$, which is given by the coupled Painlev\'e III system. This system of differential equations has the affine Weyl group symmetry of type $A_5^{(2)}$.
