Query: Existence of Kirillov-Reshetikhin crystals of type $G_2^{(1)}$ and
  $D_4^{(3)}$   In this paper we prove that every Kirillov-Reshetikhin module of type
$G_2^{(1)}$ and $D_4^{(3)}$ has a crystal pseudobase (crystal base modulo
signs), by applying the criterion for the existence of a crystal pseudobase due
to Kang et al.
