Now we consider a 50 × 50 array of cells that can communicate over long ranges as shown on the top. The critical pattern space is the 2-dimensional space spanned by the vectors on the left. Since the critical pattern space is 2-dimensional, a bifurcation is not guaranteed; however, our simulations of Delta and Notch (top right and bottom right, respectively) show that the pattern of cell fates is in the critical eigenspace, demonstrating that the theory still has merit in more degenerate cases
