“…Note for comparison to the previous case that now r = −10 :the lower difference between sums of columns shows qualitative shape changes for mismatch between columns. in [15], where only the caustic and ridge curves were given. Now r = v = 0, and the two Regge conjugates are again identical, but the coalescence is now of both the North and South gates with the West gate, on the full line from the lower left to the upper left corners of the screen, As noted in [15], since a, b and x are smaller than c, d and y, we can regard this plot as that of a 3j symbol, ( : : : ) where the entries in the upper row are the angular momenta 100, 100, x and the corresponding projections in the lower row are y -1000, 1000y, 0.…”
