AbstractThe toric ideals of 3×3 transportation polytopes
$\mathsf{T}_{\mathbf{rc}}$
are quadratically generated. The only exception is the Birkhoff polytope B3.If
$\mathsf{T}_{\mathbf{rc}}$
is not a multiple of B3, these ideals even have square-free quadratic initial ideals. This class contains all smooth 3×3 transportation polytopes.
