%H Akimichi Takemura and Ruriko Yoshida, <a href="http://arXiv.org/abs/math.CO/0605479">Saturation points on faces of a rational polyhedral cone</a>

%e Table 1 of Takemura and Yoshida: Faces for 2 x 2 x 2 x 2 tables with three 2-marginals and a 3-marginal. The first column represents the dimension of faces, the second column represents the number of faces, the third column represents the number of nowhere saturated faces and the fourth column represents the number of almost saturated faces.
