[x1, x2, x3, x4, x5] x2+x3+x4+x5; x1+x3+x4+x5; x1+x2+x4+x5; x1+x2+x3+x5; x1+x2+x3+x4; [[-0.5,1], [-0.5,1], [-0.5,1], [-0.5,1], [-0.5,1]] # The linear function f_i(x)=\sum_{j\neq i} x_j in dimension 5. The degree of a linear function is just the sign of the determinant (assuming the box contains 0).
