So the successive angles lie at positions (5n mod 8)/8 for n =0, 1, 2, 3, . Notice that we get eight radial spokes here because we have chosen an angle 5/8, which is a rationalmultiple of a full turn an exact fraction. If instead we had used 8/13, we would have got 13 radial spokes. The true golden angle lies between these two values. It is slightly smaller than 5/8 and slightly greater than 8/13. So neither picture of perfect radial spokes is quite right as a description of primordia placed according to the golden angle.
