Code First Fractional group: 15th matrix Flip (image rollover)

Code First Fractional group: 15th matrix Flip (image rollover)

First of all, pure simulation, from the outside to the inner lap of the turn, but this method is too slow.
For example, first flip along the diagonal and then flip it one time along the horizontal midline.
