Approximate rendering. Section 3.2.4: the same SERIE and ELIRR machinery, but the cells are extremely slender — 60 by 5, three rows and twenty-four columns after the sheet rotation. T = 0 stays axis-parallel; N = 6 keeps the edges few. Stretching one direction is what Nees calls anisotropy: more macro-innovation than in figure 22. JI1 and JI2 start from JS2 and JS5 of p. 122, not from the plate’s seeds. Figure 25 follows without reseeding.
