Query: Une (nouvelle ?) construction du groupe de r\'eflexion complexe $G_{31}$   In Shephard-Todd classification of finite (complex) reflection groups, the
group $G_{31}$ appears to be the unique one in rank 4 of order 46080. We
provide here an elementary construction starting from the Weyl group of type
$B_6$.
