In 113 shell extended  I’ve worked the diagram out to the 113 shell, but instead of stopping the exclusion lines at the 113 shell, I’ve stopped them at double their number.  In other words, the exclusion line of the 77 shell will extend to the 154 shell, the 113 shell to the 226 shell.  This creates an interesting feathered effect in a halo around the main diagram which indicates to a degree where the pattern originates from.  You will notice the fan effect is most pronounced around the 1 corridor, then the 2 corridor and so on.  Is symmetry maintained in the horizontal plane?
