Every ( ^{m1} / n_{1} )
primary bulb has decoration very similar to the main bulb one (in "square"
parametrisation). So for the secondary bulbs we have simply to add one more
^{m2} / n_{2} rotation number
( ^{m1} / n_{1}
^{m2} / n_{2} ).
Note that period of a secondary bulb is n_{1} x n_{2}
product. In this way we can map all the M-set decorations.
You can determine n_{2} by the number of spokes in the largest antenna attached to a secondary decoration and the shortest spoke is located m_{2} = 1 revolutions in the counterclockwise direction from the main spoke in square limited region! But you see three spokes branching point nearby. |
At last, the J_{c}-set contains infinitely many "junction points" at which 4 distinct black regions in J are attached. And the smallest black region is located m_{1} = 1 revolutions in the counterclockwise direction from the largest central region. Again in square limited region.
